This program converts the output (neutral mass density,temperature) of an empirical thermosphere model (e.g. JB2008) on a given \configClass{grid}{gridType}.
Additionally, also the thermospheric winds estimated by using the horizontal wind model HWM 2014 can be assessed.
The time for the evaluation can be specified in \config{time}. The values will be saved together with points expressed as ellipsoidal coordinates
(longitude, latitude, height) based on a reference ellipsoid with parameters \config{R} and \config{inverseFlattening}.
