Ground magnetic perturbations associated with "Ultra-Fast Kelvin Wave (UFKW) Variations in the Surface Magnetic Field"

The data set is based on the thermosphere-ionosphere-electrodynamics general circulation model (TIEGCM) simulation results and a post-processing 3D ionospheric current and magnetic perturbation calculation, which is used in the publication "Ultra-Fast Kelvin Wave (UFKW) Variations in the Surface Magnetic Field" by Forbes et al.

Focus is on an eastward-propagating ultra-fast Kelvin wave (UFKW) packet with periods between 2-4 days and zonal wavenumber s = -1 during DOY 266-281, 2009. Two sets of simulations are provided with different lower boundary (97km) conditions: 1. forced by daily and zonal mean (S0) 2. forced by S0 and 2-7days with s=-1 perturbations with the planetary wave amplitudes increased by a factor of 1.5. For these simulations the solar flux and geomagnetic forcing is held constant. Hourly output is provided of the neutral wind, neutral temperature, and ground magnetic perturbations.
