Quick overview

As an overview, mmspy utilizes zarr as the data format to convert from CDF files and store on disk. In memory, the data are openned and wrapped, in order, with dask.array.Array for automatic chunking and lazily evaluated parallel operations, pint.Quantity for unit handling and conversion, and xarray.DataArray for dimensions and coordinates labeling, with all metadata preserved from CDF files.

In the following, we show how MMS datasets are loaded with mmspy and the basics of each of the above features. Users are encouraged to familiarize at least with xarray’s basic data structures. While knowledge of pint and dask internals are good to know, there is generally no need to dig too deep into it, since all the main features can be accessed via xarray.

Query parameters and data stores

The two main components of mmspy are mmspy.query and mmspy.store. The former is an interface for setting the query parameters for the LASP SDC web services. The latter is an interface for managing both local (on machine) and remote (on the SDC) storages (aka data ‘stores’). By default, mmspy.store is set to the system’s data path:

import mmspy as mms

mms.store.show()

/ (system path: /home/docs/.local/share/mmspy)
├── local
└── remote

The path can be changed, for example, by setting:

mms.store.path = "./data.zarr/quick-overview"
mms.store.show()

/ (system path: data.zarr/quick-overview)
├── local
└── remote

Tip

Provide a path, e.g., “local/mms1/fgm” to mmspy.store.show() to list a store’s content.

Note

By default, a 'local' store is always initialized under the root directory.

Note

Interactive 'remote' store exploration is a planned feature. We are deciding how best to do this web-scraping on the SDC.

mmspy.store handles the synchronization from the remote store to the 'local' store, wherein CDF files from the remote are converted to zarr storages locally. mmspy.store also manages the reading and writing of MMS datasets from any data store under the root path.

By default, mmspy.query is empty:

mms.query.show()

  * start_time        : NaT
  * stop_time         : NaT
  * probe             : None (Alias: None)
  * instrument        : None (Alias: None)
  * data_rate         : None (Alias: None)
  * data_type         : None (Alias: None)
  * data_level        : None (Alias: None)
  * ancillary_product : None (Alias: None)

It is a good idea to browse the remote store in the SDC (and the documentation for Query) to get an idea of what values for query parameters are allowed. Typically, the CDF files are organized as probe/instrument/data_rate/data_level/data_type/**/*.cdf on the SDC, which will be converted to probe/instrument/data_type/data_rate/data_level/zarr_* locally.

Note

The order of the local path is inverted to put data_type after instrument, because typically data_rate and data_level do not vary much in the same project.

Loading MMS datasets

mmspy provides a high-level mmspy.load() method that handles mmspy.query and mmspy.store under the hood. mmspy.load() takes Query parameters as arguments and returns a (pint quantified) xarray.Dataset.

To get the Fluxgate Magnetometers (FGM) dataset, run:

fgm = mms.load(
    store="remote",
    start_time="2015-10-16T08:00:00",
    stop_time="2015-10-16T14:00:00",
    probe="mms1",
    instrument="fgm",
    data_rate="srvy",
    data_level="l2",
)

26-Mar-20 03:59:44 [INFO] Query is set from 2015-10-16 08:00:00 to 2015-10-16 14:00:00.

26-Mar-20 03:59:51 [INFO] Synchronized remote store mms1/fgm/srvy/l2 to local store local/mms1/fgm/bfield/srvy/l2.

mmspy.store should now show the zarr files on the local storage:

mms.store.show("*")

  Level2 Flux Gate Magnetometer Combined Fast/Slow Survey DC Magnetic Field for MMS Satellite Number 1

  MODS :

  version X=4: First version for public release of L2. Renamed variables to conform with new MMS variable name guidelines (obs_instr_paramName[_coordSys]_mode_level): Mag field parameters include 'b' for paramName. Use 'r' instead of 'pos' for S/C position paramName. Eliminated 'rate', replaced with 'bdeltahalf'. Added 'rdeltahalf'. l1a_mode is now just 'mode'. version X=3: fixed removal of overlap between modes. fixed a bug that caused stemp and etemp to be empty. version X=2: flag parameter name corrected: was 'status' added bits 4, 5, 6 to flag saturation on B1, B2, and B3, respectively added bit 7 to flag bad data at range changes Added etemp and l1a_mode parameters. rate, hirange, and stemp parameters now comply with MMS CDF Guidlelines, e.g. FILLVAL now defined for stemp and etemp, and is set to !values.f_nan No longer use Var_Parents attribute in stemp -- see Parents instead In this version, temperature-corrected gains are applied. Reference temperatures are used when stemp or etemp are set to FILLVAL. Non-linearity correction is applied to high rage DFG data. version X=1: added 'flag', rate and hirange parameters (but 'flag' is actually called 'status')

  TEXT :

  ['The Fluxgate Magnetometers (FGM) on Magnetospheric Multiscale consist of a traditional Analog Fluxgate Magnetometer (AFG), and a Digital Fluxgate magnetometer (DFG). The dual magnetometers are operated as a single instrument providing a single intercalibrated data product. Range changes occur at different times on the two instruments so the gains checked each periapsis can be carried out unambiguously to apoapsis. Cross correlation of calibration parameters can separate causes of the any apparent calibration changes. Use of Electron Drift Instrument (EDI) to determine the field along the rotation axis allows accurate monitoring of the zero levels along the rotation axis. Prior to launch the magnetometers were calibrated at the Technical University, Braunschweig, except for the AFG magnetometers on MMS3 and MMS4, which were calibrated at UCLA. Both sets of sensors are operated for the entire MMS orbit, with slow survey (8 samples per second) outside of the Region of Interest (ROI), and fast survey (16 samples per second) inside the ROI. Within the ROI burst mode data (128 samples per second) are also acquired. A detailed description of the MMS fluxgate magnetometers, including science objectives, instrument description, calibration, magnetic cleanliness program, and data flow can be found at http://link.springer.com/article/10.1007%2Fs11214-014-0057-3 (DOI 10.1007/s11214-014-0057-3).Additional information can also be found at http://www-spc.igpp.ucla.edu/ssc/mms (UCLA),and http://www.iwf.oeaw.ac.at (IWF, Graz).', 'For the purpose of creating a unified FGM Level2 data product, burst mode data is taken from DFG and survey mode data is taken from AFG. Because AFG and DFG are cross-calibrated on an orbit-averaged basis, small differences in offset may be observed between Level2 burst and survey mode data. Consequently, any differences are within the error of the measurement. Based on preliminary analysis of the data, the absolute error within the Region of Interest (ROI) is estimated to be no more than 0.1 nT in the spin-plane, 0.15 nT along the spin-axis and 0.2 nT in total magnitude.']

we see that it is described by Dimensions, Coordinates, Data variables, and Attributes. Dimensions describe the shape (degrees of freedom) of arrays. Coordinates label the dimensions, and there can be many coordinates along each dimension. Data variables contain data through the data property, described by both dimensions and coordinates. Attributes attrs are dictionaries containing the metadata describing a Dataset or DataArray.

Let us print a variable from the fgm dataset, say the GSE magnetic field:

b_gse has its own dimensions (time and rank_1, i.e., the spatial components), coordinates (time stamps and x,y,z labels), and has its own attrs attached.

Let us examine its data:

fgm.b_gse.data

This is a pint.Quantity which, somewhat similar to astropy.units.Quantity, is an array with units and magnitude properties. Peeling further:

is a dask.array.Array, which gives a numpy.ndarray when calling compute():

fgm.b_gse.data.magnitude.compute()

array([[16.745697 ,  1.1965685, 38.113667 ],
       [16.739008 ,  1.2021502, 38.11868  ],

Instead of evaluating operations for numerical results, dask calculates task graphs that plan out the calculations for each data chunk (and how to merge them). Task graphs are automatically optimized and are evaluated when compute() is called. In the dask section below, we provide an example of calculating a complicated graph.

Note that in regular usage, a user does not need to perform the above decomposition steps, since both pint.Quantity and dask.array.Array are exposed in xarray API. compute() can be called on xarray.Dataset and xarray.DataArray:

  Level2 Flux Gate Magnetometer Combined Fast/Slow Survey DC Magnetic Field for MMS Satellite Number 1

  MODS :

  version X=4: First version for public release of L2. Renamed variables to conform with new MMS variable name guidelines (obs_instr_paramName[_coordSys]_mode_level): Mag field parameters include 'b' for paramName. Use 'r' instead of 'pos' for S/C position paramName. Eliminated 'rate', replaced with 'bdeltahalf'. Added 'rdeltahalf'. l1a_mode is now just 'mode'. version X=3: fixed removal of overlap between modes. fixed a bug that caused stemp and etemp to be empty. version X=2: flag parameter name corrected: was 'status' added bits 4, 5, 6 to flag saturation on B1, B2, and B3, respectively added bit 7 to flag bad data at range changes Added etemp and l1a_mode parameters. rate, hirange, and stemp parameters now comply with MMS CDF Guidlelines, e.g. FILLVAL now defined for stemp and etemp, and is set to !values.f_nan No longer use Var_Parents attribute in stemp -- see Parents instead In this version, temperature-corrected gains are applied. Reference temperatures are used when stemp or etemp are set to FILLVAL. Non-linearity correction is applied to high rage DFG data. version X=1: added 'flag', rate and hirange parameters (but 'flag' is actually called 'status')

  TEXT :

  ['The Fluxgate Magnetometers (FGM) on Magnetospheric Multiscale consist of a traditional Analog Fluxgate Magnetometer (AFG), and a Digital Fluxgate magnetometer (DFG). The dual magnetometers are operated as a single instrument providing a single intercalibrated data product. Range changes occur at different times on the two instruments so the gains checked each periapsis can be carried out unambiguously to apoapsis. Cross correlation of calibration parameters can separate causes of the any apparent calibration changes. Use of Electron Drift Instrument (EDI) to determine the field along the rotation axis allows accurate monitoring of the zero levels along the rotation axis. Prior to launch the magnetometers were calibrated at the Technical University, Braunschweig, except for the AFG magnetometers on MMS3 and MMS4, which were calibrated at UCLA. Both sets of sensors are operated for the entire MMS orbit, with slow survey (8 samples per second) outside of the Region of Interest (ROI), and fast survey (16 samples per second) inside the ROI. Within the ROI burst mode data (128 samples per second) are also acquired. A detailed description of the MMS fluxgate magnetometers, including science objectives, instrument description, calibration, magnetic cleanliness program, and data flow can be found at http://link.springer.com/article/10.1007%2Fs11214-014-0057-3 (DOI 10.1007/s11214-014-0057-3).Additional information can also be found at http://www-spc.igpp.ucla.edu/ssc/mms (UCLA),and http://www.iwf.oeaw.ac.at (IWF, Graz).', 'For the purpose of creating a unified FGM Level2 data product, burst mode data is taken from DFG and survey mode data is taken from AFG. Because AFG and DFG are cross-calibrated on an orbit-averaged basis, small differences in offset may be observed between Level2 burst and survey mode data. Consequently, any differences are within the error of the measurement. Based on preliminary analysis of the data, the absolute error within the Region of Interest (ROI) is estimated to be no more than 0.1 nT in the spin-plane, 0.15 nT along the spin-axis and 0.2 nT in total magnitude.']

Note

By default, when mmspy.load(store="remote") is called a second time, mmspy checks if the local zarr files are updated with the remote, and calls mmspy.load(store="local") if they are to avoid downloading the same file twice.

Note that this makes it very convenient to switch between 'remote' and 'local', and any secondary (or tertiary, and so on and so forth) data stores. This allows a research project to mutate and combine different MMS datasets through many stages to obtain publication-worthy results! More on this later.

Persistent query

When provided as arguments for mmspy.load(), the query parameters are not remembered. Thus, after the load() call is finished, mmspy.query is still empty:

mms.query.show()

  * start_time        : NaT
  * stop_time         : NaT
  * probe             : None (Alias: None)
  * instrument        : None (Alias: None)
  * data_rate         : None (Alias: None)
  * data_type         : None (Alias: None)
  * data_level        : None (Alias: None)
  * ancillary_product : None (Alias: None)

To make the query persistent, assign the parameters directly into mmspy.query:

mms.query.start_time = "2015-10-16T08:00:00"
mms.query.stop_time = "2015-10-16T14:00:00"
mms.query.probe = "mms1"
mms.query.data_rate = "fast"
mms.query.data_level = "l2"
mms.query.show()

  * start_time        : 2015-10-16 08:00:00
  * stop_time         : 2015-10-16 14:00:00
  * probe             : mms1 (Alias: mms1)
  * instrument        : None (Alias: None)
  * data_rate         : fast (Alias: fast)
  * data_type         : None (Alias: None)
  * data_level        : l2 (Alias: l2)
  * ancillary_product : None (Alias: None)

This shortens the necessary parameters to specify for later load() calls. For example, the Electric Double Probes (EDP) dataset can be loaded with:

edp = mms.load(instrument="edp", data_type="dce")
edp

  TEXT :

  FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s) resolution. Per mission design, not all burst-resolution data are downlinked, but all survey data are downlinked. Planning around calibration activities, avoidance of Earth radiation belts, etc, when possible, FPI usually operates in Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments product contains results from integrating the standard moments of phase-space distributions formed from the indicated data type (DES/DIS burst, FS or SS). For convenience, some additional parameters are included to augment those most commonly found in a moments product of this sort, plus time-stamps and other annotation characterizing the state of the instrument system at the indicated time.

FEEPS dataset

FGM, EDP, and FPI datasets are mostly simple in terms of metadata. However, FEEPS is one of more complicated cases where the variables and metadata in the CDF files can be overwhelming. mmspy provides an automatic autoformatting that turns the FEEPS dataset into a more readable form (without altering the data):

ion_feeps = mms.load(instrument="feeps", data_rate="srvy", data_type="ion")

Masking flagged data

Data from the level-2 CDF files are not fault-free, and many instruments have caveats that one should read about in the product guides before using the data. For convenience, mmspy provides instrument-specific xarray accessors (fgm, edp, fpi, feeps) that allows for automatic data masking in accordance with the Calibration and Measurement Algorithms document (CMAD) and in consistency with PySPEDAS. The FEEPS masking is the most complicated, which uses multiple time-dependent and time-independent energy tables. Simply call the following and bad eyes will be set to NaN:

ion_feeps = ion_feeps.feeps.mask_data()

Unit handling and conversions

astropy.units is the more common library for units handling. However, xarray currently cannot wrap astropy quantities until Quantity 2.0 is implemented. Thus, mmspy resorts to utilizing pint and pint-xarray for units handling and conversions. One setback is that pint does not accept FITS-compliant strings (e.g., 'cm-2 s-1 sr-1'). Thus, users familiar with astropy.units may find it difficult to migrate to pint. As a resolution, mmspy implements a custom pint formatter for FITS unit strings that makes the pint experience as close to that of astropy.units as much as possible. This formatter is initialized when mmspy is imported.

Below is an example of using the custom mmspy.units registry for calculating the ion cyclotron frequency:

from mmspy import units as u
import numpy as np

background_field = u.Quantity(50.0, "nT")
proton_gyrofrequency = (u.e * background_field / u.m_p / 2 / np.pi).to("Hz")
proton_gyrofrequency

0.7622593218805414 hertz

Tip

mmspy.units is an application-level registry. Thus, it can also be imported with from pint import application_registry as u.

xarray.Dataset loaded with mmspy.load() are quantified with pint by default. To do the same conversion above with a magnetic field data array, use the pint accessor:

background_field = fgm.b_gse.tensor.magnitude
fci = (u.e * background_field / u.m_p / 2 / np.pi).pint.to("Hz")
fci.data.compute()

Magnitude	[0.6349216201279423 0.6349530242442917 0.6351533127196759 ... 0.5492489808073479 0.5490516001205145 0.5490270583851451]
Units	hertz

Above, tensor is an accessor provided by mmspy to conveniently calculate the magnitude of rank_1 and rank_2 tensors.

Tip

Dequantify a Dataset or DataArray with dequantify(). For example, fgm.b_gse.pint.dequantify() returns a DataArray with the pint wrapping layer removed, where the units will be saved in its attrs. In opposite, fgm.b_gse.pint.quantify() will rewrap the array with pint.Quantity.

Furthermore, mmspy provides convienient conversion species-dependent parameters, so that one can directly convert by specifying what species the conversion involves:

fce = background_field.data.to("Hz", "electron")
fce.compute()

Magnitude	[1165.8130302110483 1165.8706929632397 1166.238453182772 ... 1008.5049844834606 1008.1425634076496 1008.0975010346407]
Units	hertz

Note

Conversion to frequency by mmspy is always to ordinary frequency (unit 'Hz').

Unfortunately, this conversion is not implemented within the pint accessor. So one would have to detach the data from the xarray manually (via data), convert it to desired units, and then put the data back into the xarray. For example:

fce = background_field.copy()
fce.data = fce.data.to("Hz", "electron")
fce.compute()

  Level2 Flux Gate Magnetometer Combined Fast/Slow Survey DC Magnetic Field for MMS Satellite Number 1

  MODS :

  version X=4: First version for public release of L2. Renamed variables to conform with new MMS variable name guidelines (obs_instr_paramName[_coordSys]_mode_level): Mag field parameters include 'b' for paramName. Use 'r' instead of 'pos' for S/C position paramName. Eliminated 'rate', replaced with 'bdeltahalf'. Added 'rdeltahalf'. l1a_mode is now just 'mode'. version X=3: fixed removal of overlap between modes. fixed a bug that caused stemp and etemp to be empty. version X=2: flag parameter name corrected: was 'status' added bits 4, 5, 6 to flag saturation on B1, B2, and B3, respectively added bit 7 to flag bad data at range changes Added etemp and l1a_mode parameters. rate, hirange, and stemp parameters now comply with MMS CDF Guidlelines, e.g. FILLVAL now defined for stemp and etemp, and is set to !values.f_nan No longer use Var_Parents attribute in stemp -- see Parents instead In this version, temperature-corrected gains are applied. Reference temperatures are used when stemp or etemp are set to FILLVAL. Non-linearity correction is applied to high rage DFG data. version X=1: added 'flag', rate and hirange parameters (but 'flag' is actually called 'status')

  TEXT :

  ['The Fluxgate Magnetometers (FGM) on Magnetospheric Multiscale consist of a traditional Analog Fluxgate Magnetometer (AFG), and a Digital Fluxgate magnetometer (DFG). The dual magnetometers are operated as a single instrument providing a single intercalibrated data product. Range changes occur at different times on the two instruments so the gains checked each periapsis can be carried out unambiguously to apoapsis. Cross correlation of calibration parameters can separate causes of the any apparent calibration changes. Use of Electron Drift Instrument (EDI) to determine the field along the rotation axis allows accurate monitoring of the zero levels along the rotation axis. Prior to launch the magnetometers were calibrated at the Technical University, Braunschweig, except for the AFG magnetometers on MMS3 and MMS4, which were calibrated at UCLA. Both sets of sensors are operated for the entire MMS orbit, with slow survey (8 samples per second) outside of the Region of Interest (ROI), and fast survey (16 samples per second) inside the ROI. Within the ROI burst mode data (128 samples per second) are also acquired. A detailed description of the MMS fluxgate magnetometers, including science objectives, instrument description, calibration, magnetic cleanliness program, and data flow can be found at http://link.springer.com/article/10.1007%2Fs11214-014-0057-3 (DOI 10.1007/s11214-014-0057-3).Additional information can also be found at http://www-spc.igpp.ucla.edu/ssc/mms (UCLA),and http://www.iwf.oeaw.ac.at (IWF, Graz).', 'For the purpose of creating a unified FGM Level2 data product, burst mode data is taken from DFG and survey mode data is taken from AFG. Because AFG and DFG are cross-calibrated on an orbit-averaged basis, small differences in offset may be observed between Level2 burst and survey mode data. Consequently, any differences are within the error of the measurement. Based on preliminary analysis of the data, the absolute error within the Region of Interest (ROI) is estimated to be no more than 0.1 nT in the spin-plane, 0.15 nT along the spin-axis and 0.2 nT in total magnitude.']

  TEXT :

  FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s) resolution. Per mission design, not all burst-resolution data are downlinked, but all survey data are downlinked. Planning around calibration activities, avoidance of Earth radiation belts, etc, when possible, FPI usually operates in Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments product contains results from integrating the standard moments of phase-space distributions formed from the indicated data type (DES/DIS burst, FS or SS). For convenience, some additional parameters are included to augment those most commonly found in a moments product of this sort, plus time-stamps and other annotation characterizing the state of the instrument system at the indicated time.

  TEXT :

  FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s) resolution. Per mission design, not all burst-resolution data are downlinked, but all survey data are downlinked. Planning around calibration activities, avoidance of Earth radiation belts, etc, when possible, FPI usually operates in Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments product contains results from integrating the standard moments of phase-space distributions formed from the indicated data type (DES/DIS burst, FS or SS). For convenience, some additional parameters are included to augment those most commonly found in a moments product of this sort, plus time-stamps and other annotation characterizing the state of the instrument system at the indicated time.

Energy flux can be converted (relativistically correctly) to phase space density (a bit more involved, since the conversion involves energy) as follows:

ion_fpi = ion_fpi.assign_coords(
    f_omni=(
        ion_fpi.energyspectr_omni.dims,
        ion_fpi.energyspectr_omni.data.to(

            "ion",
            energy=ion_fpi.energy.broadcast_like(ion_fpi.energyspectr_omni).data,
        ),
    ),
)

  TEXT :

  FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s) resolution. Per mission design, not all burst-resolution data are downlinked, but all survey data are downlinked. Planning around calibration activities, avoidance of Earth radiation belts, etc, when possible, FPI usually operates in Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments product contains results from integrating the standard moments of phase-space distributions formed from the indicated data type (DES/DIS burst, FS or SS). For convenience, some additional parameters are included to augment those most commonly found in a moments product of this sort, plus time-stamps and other annotation characterizing the state of the instrument system at the indicated time.

These layers show all of the necessary steps to get from data on-disk to the final computational results in-memory, which is the ion speed quantified in 'km/s'. The benefit of using dask adds up quickly for more complicated operations, which could easily result in a graph of hundreds of layers.

As a demonstration, let us further complicate the calculations by trying to integrate for the number density using the omni-directional phase space density ion_fpi.f_omni. Usually, there are important preprocessing steps to obtain the correct plasma moments. But let us ignore them for now. Perform a regrid in the ion speed (see more detailed examples in the Gallery):

from mmspy.compute.particle import ParticleGrid, interpolate_distribution
import numpy as np

grid = {
    "V": ParticleGrid(
        name="speed",
        center=u.Quantity(np.linspace(0, 5000, 30), "km s-1")
    ),
}
f_interpolated = interpolate_distribution(ion_fpi, grid, variable="f_omni")

And finally integrate along the speed coordinate, convert to number density, and add a factor of 2pi (because f_omni is solid-angle averaged):

V = f_interpolated.V
f_interpolated = f_interpolated.fillna(0.0)  # Fill NaNs with zeros
n = 2 * np.pi * (V**2 * f_interpolated).integrate("V").pint.to("cm-3")

Plotting

mmspy does not provide any interactive component. Plotting is deferred to matplotlib, which is the most common scientific visualization library in Python. However, mmspy does provide a custom matplotlib stylesheet and some convenient formatting methods for time series and spectrograms.

To use the stylesheet:

mms.configure_matplotlib()

26-Mar-20 04:01:10 [INFO] Using stylesheet /home/docs/checkouts/readthedocs.org/user_builds/mmspy/checkouts/stable/src/mmspy/data/mmspy.mplstyle

Nothing else is required. Let us now compare the integrated moment in the previous section with the L2 density using matplotlib:

import matplotlib.pyplot as plt

fig, ax = plt.subplots(1, 1, figsize=(12, 6))

ax.plot(ion_fpi.time, ion_fpi.numberdensity, "-k", label="L2 density")
ax.plot(n_integrated.time, n_integrated, "-r", label="Integrated density")
ax.legend(frameon=False, loc="upper right")
ax.set_ylabel(f"{n_integrated.pint.units:latex}")

mms.plot.autoformat(ax)
plt.show()

Not too bad! There are some expected discrepancy, mainly due to the usage of a linear grid. A more detailed example on how to use functions in the mmspy.compute.particle module is given in the Gallery.

Alias query parameters and variables

You might have noticed prior that mmspy.query shows aliases for the parameters. This option is available if you wish to customize different names for datasets and variables. There is actually another important component of mmspy, called mmspy.config, which configures the behaviors of mmspy.query and mmspy.store. To enable aliasing, set:

mms.config.query.use_alias = True

mms.query.data_rate = "survey"
mms.query.data_level = "level_2"
mms.query.show()

  * start_time        : 2015-10-16 08:00:00
  * stop_time         : 2015-10-16 14:00:00
  * probe             : mms1 (Alias: mms1)
  * instrument        : None (Alias: None)
  * data_rate         : survey (Alias: survey)
  * data_type         : None (Alias: None)
  * data_level        : l2 (Alias: level_2)
  * ancillary_product : None (Alias: None)

By default, 'survey' is aliased to 'srvy' for fgm,scm,fsm,hpca,feeps, and 'fast' for edp,fpi. And the data variables are renamed to be more verbose. However, this can be customized by changing mmspy.config.

Note

The code still works if the actual values are provided in place of the aliases.

Tip

Print out mmspy.config to examine the default aliases.

fgm = mms.load(instrument="fgm")

  Level2 Flux Gate Magnetometer Combined Fast/Slow Survey DC Magnetic Field for MMS Satellite Number 1

  MODS :

  version X=4: First version for public release of L2. Renamed variables to conform with new MMS variable name guidelines (obs_instr_paramName[_coordSys]_mode_level): Mag field parameters include 'b' for paramName. Use 'r' instead of 'pos' for S/C position paramName. Eliminated 'rate', replaced with 'bdeltahalf'. Added 'rdeltahalf'. l1a_mode is now just 'mode'. version X=3: fixed removal of overlap between modes. fixed a bug that caused stemp and etemp to be empty. version X=2: flag parameter name corrected: was 'status' added bits 4, 5, 6 to flag saturation on B1, B2, and B3, respectively added bit 7 to flag bad data at range changes Added etemp and l1a_mode parameters. rate, hirange, and stemp parameters now comply with MMS CDF Guidlelines, e.g. FILLVAL now defined for stemp and etemp, and is set to !values.f_nan No longer use Var_Parents attribute in stemp -- see Parents instead In this version, temperature-corrected gains are applied. Reference temperatures are used when stemp or etemp are set to FILLVAL. Non-linearity correction is applied to high rage DFG data. version X=1: added 'flag', rate and hirange parameters (but 'flag' is actually called 'status')

  TEXT :

  ['The Fluxgate Magnetometers (FGM) on Magnetospheric Multiscale consist of a traditional Analog Fluxgate Magnetometer (AFG), and a Digital Fluxgate magnetometer (DFG). The dual magnetometers are operated as a single instrument providing a single intercalibrated data product. Range changes occur at different times on the two instruments so the gains checked each periapsis can be carried out unambiguously to apoapsis. Cross correlation of calibration parameters can separate causes of the any apparent calibration changes. Use of Electron Drift Instrument (EDI) to determine the field along the rotation axis allows accurate monitoring of the zero levels along the rotation axis. Prior to launch the magnetometers were calibrated at the Technical University, Braunschweig, except for the AFG magnetometers on MMS3 and MMS4, which were calibrated at UCLA. Both sets of sensors are operated for the entire MMS orbit, with slow survey (8 samples per second) outside of the Region of Interest (ROI), and fast survey (16 samples per second) inside the ROI. Within the ROI burst mode data (128 samples per second) are also acquired. A detailed description of the MMS fluxgate magnetometers, including science objectives, instrument description, calibration, magnetic cleanliness program, and data flow can be found at http://link.springer.com/article/10.1007%2Fs11214-014-0057-3 (DOI 10.1007/s11214-014-0057-3).Additional information can also be found at http://www-spc.igpp.ucla.edu/ssc/mms (UCLA),and http://www.iwf.oeaw.ac.at (IWF, Graz).', 'For the purpose of creating a unified FGM Level2 data product, burst mode data is taken from DFG and survey mode data is taken from AFG. Because AFG and DFG are cross-calibrated on an orbit-averaged basis, small differences in offset may be observed between Level2 burst and survey mode data. Consequently, any differences are within the error of the measurement. Based on preliminary analysis of the data, the absolute error within the Region of Interest (ROI) is estimated to be no more than 0.1 nT in the spin-plane, 0.15 nT along the spin-axis and 0.2 nT in total magnitude.']

  TEXT :

  FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s) resolution. Per mission design, not all burst-resolution data are downlinked, but all survey data are downlinked. Planning around calibration activities, avoidance of Earth radiation belts, etc, when possible, FPI usually operates in Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments product contains results from integrating the standard moments of phase-space distributions formed from the indicated data type (DES/DIS burst, FS or SS). For convenience, some additional parameters are included to augment those most commonly found in a moments product of this sort, plus time-stamps and other annotation characterizing the state of the instrument system at the indicated time.
