Database for "A New Four-Component L*-dependent Model for Radial Diffusion based on Solar Wind and Magnetospheric Drivers of ULF Waves"

Database for "A New Four-Component L*-dependent Model for Radial Diffusion based on Solar Wind and Magnetospheric Drivers of ULF Waves" submitted to Space Weather by Murphy et al. 

The repository contains 2 datasets:

The power spectral density of the compressional magnetic field from THEMIS, Van Allen Probes, and GOES along with accompanying position (MLT, L, L* TS05), solar wind, and geomagnetic data

The power spectral density of the azimuthal electric field from THEMIS and Van Allen Probes along with accompanying position (MLT, L, L* TS05), solar wind, and geomagnetic data

Both datasets are provided as an IDL save file and as an HDF5 file.

The IDL data can be loaded using: 

filename='electric_field_psd.sav'
filename='magnetic_field_psd.sav'

restore, filename, /verbose

The HDF5 file can be opened and investigate using (small changes will be required to store each variable):

import h5py

filename = 'magnetic_field_psd.h5' # magnetic field data
filename = 'magnetic_field_psd.h5' # electric field data

with h5py.File(filename, "r") as f:
    # loop through all keys (data)
    #print key and key attribute and size
    for i in f.keys():
    print(f"{i} - {f[i].attrs['attributes']}, shape - {f[i].shape}")
    ds_obj = f[i]      # returns as a h5py dataset object
    ds_arr = f[i][()]  # returns as a numpy array

Below is a description of unique and common variables in each file. The psd variables have a shape [f,t], indicating the first dimension is frequency and the second is time, the f_mhz variable has shape [f], and all time series have shape [t]; here [f] and [t] denotes the number of elements in frequency and time arrays.
