NRLMSIS
Version: 2.1NRLMSIS 2.1 includes an empirical model of nitric oxide (NO) number density at altitudes from ∼73 km to the exobase, as a function of altitude, latitude, day of year, solar zenith angle, solar activity, and geomagnetic activity. This upgrade to NRLMSIS 2.0 consists solely of the addition of NO. MSIS 2.1 assimilates observations from six space-based instruments: UARS/HALOE, SNOE, Envisat/MIPAS, ACE/FTS, Odin/SMR, and AIM/SOFIE.
Inputs
The inputs for the model are:
Year and day
time of day
geodetic altitude from 0 to 1,000 km
geodetic latitude longitude
local apparent solar time
81-day average of F10.7 solar flux
daily F10.7 solar flux for previous day
Daily magnetic index
Outputs
Output of the model includes:
Helium number density
Oxygen(O) number density
Oxygen (O2) number density
