NmF2 from LEO satellites (CHAMP and COSMIC) and ISRs

Model output file format:
Year DOY Hour Min Sec Lat[deg] Lon[deg] NmF2[1/cm3]
Here DOY is day of year, andNmF2 [1/cm3] is maximum electron density from either LEO satellites or ISRs. Lat [deg] and Lon [deg] for NmF2 from ISRs are geographic latitude and longitude of ISRs. For NmF2 from LEO radio occultation measurements, Hour, Min, Sec, Lat [deg] and Lon [deg] are universal time and geographic location at which maximum electron density occurs that are not on the satellite track.
