Efficiency of Electromagnetic Energy Transfer from Solar Wind to Ionosphere through Magnetospheric Ultra-Low Frequency Waves

This data repository contains necessary data files and plotting scripts that support Lin et al. Efficiency of Electromagnetic Energy Transfer from Solar Wind to Ionosphere through Magnetospheric Ultra-Low Frequency Waves. PF_fig_PF.nc.nc contains (a) 5-200 s bandpassed Alfvenic field-aligned Poynting flux (SA//) mapped to the ionospheric altitude and averaged over the four-hour interval. (b) 5-200s bandpassed SA// in the meridional plane of magnetic local time of 7. (c) 4.5-5.5 mHz root-integrated power (RIP) of radial electric field Er in the equatorial plane. (d) 4.5-5.5 mHz RIP of azimuthal magnetic field Bϕ in the meridional plane of 7 MLT. (e-f) Field-aligned keograms of transverse electric field and azimuthal magnetic field along the field line with the largest SA// PF_fig_JH.nc.nc contains (a) average quasi-static Poynting flux and (b) average FAC/convection potential contour in the baseline run using 200 s source period and 5 S Pedersen conductance; and Poynting flux dependence on (c) source period and (d) ionospheric Pedersen conductance.
