Latitude-longitude distribution and NmF2 simulation

The effects of IMF By on the middle thermosphere during a geomagnetically “quiet” period at solar minimum

The polar view of the percentage difference of simulated ∑O/N2 and GOLD observed ∑O/N2 between DOY 111 and 110 at 15:10 UT in 2019. The perimeter latitude is 30°N
