The following instructions provide a guide for installing pysatNASA and give some examples on how to use the routines
pysatNASA uses common Python modules, as well as modules developed by and for the Space Physics community. This module officially supports Python 3.6+.
| Common modules | Community modules | Optional Modules |
|---|---|---|
| beautifulsoup4 | cdflib>=0.4.4 | pysatCDF |
| lxml | pysat>=3.1.0 | |
| netCDF4 | ||
| numpy | ||
| pandas | ||
| requests | ||
| xarray |
pip install pysatNASA
git clone https://github.com/pysat/pysatNASA.git
Change directories into the repository folder and build the project. For a local install use the "--user" flag after "install".
cd pysatNASA/
pip install .
pysatNASA is currently in an initial development phase and requires pysat 3.1.0.
Feedback and contributions are appreciated.
The instrument modules are portable and designed to be run like any pysat instrument.
import pysat
from pysatNASA.instruments import icon_ivm
ivm = pysat.Instrument(inst_module=icon_ivm, inst_id='a')
Another way to use the instruments in an external repository is to register the
instruments. This only needs to be done the first time you load an instrument.
Afterward, pysat will identify them using the platform and name keywords.
import pysat
pysat.utils.registry.register(['pysatNASA.instruments.icon_ivm'])
ivm = pysat.Instrument('icon', 'ivm', inst_id='a')
For data products stored as CDF files, this package can use either cdflib or
pysatCDF. Note that cdflib is a pure python package and more readily
deployable across systems, whereas pysatCDF interfaces with the fortran.
This is a faster approach for loading data, but may not install on all systems.
There are known issues with numpy>=1.24. Therefore, pysatCDF is optional
rather than required.
You can specify which load routine to use via the optional use_cdflib kwarg.
If no kwarg is specified, pysatNASA will default to pysatCDF if it is
successfully installed, and default to cdflib otherwise.
ivm = pysat.Instrument('cnofs', 'ivm', use_cdflib=True)
