A simple and small python package for handling and processing heliospheric satellite data. The current primary features are automatic data downloading & crude processing for Bepi, DSCOVR, MES, PSP, SolO, STA, STB, VEX, and Wind data. Furthermore all related and required SPICE kernels are downloaded & loaded automatically when required.

Install the latest version manually using git:

git clone https://github.com/ajefweiss/HelioSat
cd HelioSat
pip install .

or slightly older versions from PyPi with pip install HelioSat

Import the heliosat module and create a satellite instance:

import heliosat

wind_sat = heliosat.WIND()

This will automatically download and load any required SPICE kernels (using spiceypy). Note that kernel or data files will be stored in ~/.heliosat by default. As this may use up alot of disk space you can alternatively change the default path by setting the environment variable HELIOSAT_DATAPATH.

Querying data (any tz-unaware datetime objects are assumed to be UTC) can then be done using:

t_query = ["2020-01-01T00:00:00"]
wind_t, wind_data = wind_sat.get(t_query, "mfi_h0", frame="GSE", return_datetimes=True)

By default only values at given datetimes are returned, if you need a time range you can either manually generate an extensive list of dates or use:

t_query_range = ["2020-01-01T00:00:00", "2020-01-02T00:00:00"]
wind_t, wind_data = wind_sat.get(t_query_range, "mfi_h0", as_endpoints=True, frame="GSE", return_datetimes=True)
