Cluster Science Archive (CSA)

The Cluster Science Archive (CSA) provides access to all science and support data of the on-going Cluster (2000- ) and Double Star (2004-2008) missions. It’s integration into speasy makes easy to get any public data from the CSA handling both webservice API and ISTP CDF files read.

Basics: Getting data from CSA module

The easiest solution is to use your python terminal completion and browse spz.inventories.data_tree.csa to find your product. Once you have found your product, then simply ask CSA module to get data for the provided time range:

>>> import speasy as spz
>>> # Let's assume you wanted to get 'Cluster C3, Magnetic Field Vector, spin resolution in GSE'
>>> c3_fgm_spin = spz.csa.get_data(spz.inventories.data_tree.csa.Cluster.Cluster_3.FGM3.C3_CP_FGM_SPIN.B_vec_xyz_gse__C3_CP_FGM_SPIN, "2018-01-01", "2018-01-01T01")
>>> c3_fgm_spin.columns
['Bx', 'By', 'Bz']
>>> c3_fgm_spin.values
