Title: Data repository for Lin et al. (2022) "Origin of Dawnside Subauroral Polarization Streams during Major Geomagnetic Storms" Description: This dataset contains the necessary data and plotting tools supporting the paper titled "Origin of Dawnside Subauroral Polarization Streams during Major Geomagnetic Storms", by Lin et al., 2022. The data includes solar wind/IMF data on 20 November 2003, DMSP F16 measurements of electron precipitation energy flux, electron density, cross track ion drift velocity, magnetic perturbation from 13:51 UT to 14:31 UT on 20 November 2003; MAGE model simulation results of EnFlux, Vhorz, and FAC along the same DMSP trajectory; MAGE simulation results of zonal ion drift, FAC, and magnetospheric equatorial plasma pressure at 06:30 UT and 18:30 UT; MAGE/RCM outputs of ring current pressure at 06 MLT and 18 MLT; RCM outputs of effective potential; CHIMP simulation results of test particle ions at 06:30 UT and 18:30 UT.
