heliopy
A python library for Space Physics. The primary goal of this python package is to make it really easy to import common data sets used in Space Physics. Full documentation can be found here.
A quick example shows how easy it is to import and view data:
from datetime import datetime, timedelta
import heliopy.data.wind as wind
import matplotlib.pyplot as plt
starttime = datetime(2016, 1, 1, 0, 0, 0)
endtime = starttime + timedelta(hours=2)
data = wind.mfi_h0(starttime, endtime)
plt.plot(data['Bx_gse'])
plt.plot(data['By_gse'])
plt.plot(data['Bz_gse'])
plt.show()
