These are simulation results from the thermosphere-ionosphere-electrodynamics GCM
described in the manuscript "Importance of the lower atmospheric forcing and
mahnetosphere-ionosphere coupling in simulating neutral density during the February 2016
geomagnetic storm" by Maute et al. submitted to Frontiers.
The study is focused on examening the effect on the neutral density of different lower boundary
forcing and different high latitude forcing methods. The simulations are compared to Swarm-C neutral
density along the satellite orbit. 

There are 3 different TIEGCM simulations which output is provided and vary by their
forcing
1. lower atmospheric forcing by WACCM-X/SD perturbations and mean,  high latitude foricng via
field-aligned current (labeled WacXBP_FAC)
2. lower atmospheric forcing by climatological Global Scale Wave Model GSWM)
(perturbations) and climatological background, high latitude forcing via (labeled Climate_FAC)
field-aligned current
3. lower atmospheric forcing by WACCM-X/SD perturbations and mean, high latitude forcing via
Weimer empirical model (labeled WacXBP_Weimer)

There are two additional simulations for which the neutral density is provided
4. lower atmospheric forcing by WACCM-X/SD perturbations and climatological background, high latitude foricng via
field-aligned current (labeled WacXP_Bclimate_FAC)
5. lower atmospheric forcing by WACCM-X/SD symmetric perturbations (with respect to
geographic latitude) and mean, high latitude foricng via
field-aligned current (labeled WacXBPsym_FAC)
