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.astype("float32")
array([[  4.603,  13.444, -16.832],
       [  4.684,  12.852, -16.708],
       [  2.86 ,  12.794, -17.362],
       ...,
       [ 20.586,  -4.407, -29.247],
       [ 20.741,  -0.268, -29.078],
       [ 20.356,   1.052, -27.904]], shape=(852, 3), dtype=float32)
