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

description: Database for <strong>"A New Four-Component L*-dependent Model for Radial Diffusion based on Solar Wind and Magnetospheric Drivers of ULF Waves" </strong>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: <pre><code>filename='electric_field_psd.sav' filename='magnetic_field_psd.sav' restore, filename, /verbose</code></pre> The HDF5 file can be opened and investigate using (small changes will be required to store each variable): <pre><code class="language-python">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</code></pre> 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. ------------------------------------ <strong>Magnetic field data set:</strong> <strong><em>Files</em></strong> magnetic_field_psd.h5 magnetic_field_psd.sav <strong><em>Unique Data (variable in file)</em></strong> psd Power spectral density of the compressional magnetic field from THEMIS, Van Allen Probes, and GOES Units - nT<sup>2</sup>/mHz Shape - [f, t] ------------------------------------ <strong>Electric field data set:</strong> <strong><em>Files</em></strong> electric_field_psd.h5 electric_field_psd.sav <strong><em>Unique Data (variable in file)</em></strong> psd Power spectral density of the azimuthal electric field from THEMIS, Van Allen Probes, and GOES Units - (mV/m)<sup>2</sup>/mHz Shape - [f, t] ------------------------------------ <strong>Common Data in the Magnetic and Electric Field Datasets (variable in file):</strong> probe Corresponding satellite of each time stamp Shape [t] t Time stamp of each time series; number of seconds since 1970 (UNIX time), [t] Units - s Shape [t] f_mhz Frequency of psd data, [f] Units - mHz Shape [f] - (19) ae OMNI AE index of each time stamp Units - nT' Shape [t] al OMNI AL index of each time stamp, units - nT Shape [t] au OMNI AU index of each time stamp Units - nT Shape [t] b_t OMNI IMF B of each time stamp Units - nT Shape [t] b_x OMNI IMF Bx (GSM) of each time stamp Units - nT Shape [t] b_y OMNI IMF By (GSM) of each time stamp Units - nT Shape [t] b_z OMNI IMF Bz (GSM) of each time stamp Units - nT Shape [t] dst OMNI Dst of each time stamp Units - nT Shape [t] kp - OMNI Kp (Kp*10) of each time stamp units - NA Shape [t] l_sh L-shell of each time stamp Shape [t] ls_t05 L* from TS05 of each time stamp Shape [t] mlt Magnetic Local Time of each time stamp Unit - hour Shape [t] n OMNI Solar Wind Proton Density of each time stamp Units - n/cc Shape [t] pdyn OMNI Solar Wind Dynamic Pressure (flow pressure) of each time stamp Units - nPa Shape [t] symh - b'OMNI Sym-H of each time stamp, units - nT', shape - (477205,) v_t OMNI Solar wind V of each time stamp Units - km/s Shape [t] v_x OMNI Solar wind Vx (GSE) of each time stamp Units - km/s Shape [t] v_y OMNI Solar wind Vy (GSE) of each time stamp Units - km/s Shape [t] v_z OMNI Solar wind Vz (GSE) of each time stamp Units - km/s Shape [t]
