Solar wind plasma, magnetic field parameters and geomagnetic storm index SYM-H from 2000 to 2020

SYM-H index is used to quantify the intensity of geomagnetic storm. Its temporal variation is related to the solar wind plasma and magnetic field parameters. This dataset offers time series of solar wind density, solar wind velocity and solar wind magnetic field, SYM-H index. The python and matlab code files for processing and plotting data are also included. 

Methods
The dataset includes SYM-H, solar wind density, solar wind velocity, and solar wind magnetic field. All data are downloaded from the NASA/GSFC' Space Physics Data Facility's OMNI Web service(http://omniweb.gsfc.nasa.gov). The data stored in a array of Numpy named xarr1.npy. Column 1,2,3 are solar wind magnetic field vector in x, y, z direction; Column 4,5,6 are solar wind velocity  vector in x, y, z direction; Column 7 is solar wind proton number density and Column 8 is SYM-H. Row are in term of minute.  Files test_id.npy, train_id.npy and val_id.npy store the first row and the latest row of each storm for training, validation and testing in our manuscript.
