Nrlmsise-00 Empirical Model of the Atmosphere: Statistical Comparisons and Scientific Issues

摘要: [1] The new NRLMSISE-00 empirical atmospheric model extends from the ground to exobase and is a major upgrade of MSISE-90 in thermosphere. The associated NRLMSIS database now include following data: (1) total mass density satellite accelerometers orbit determination (including Jacchia Barlier data sets), (2) temperature incoherent scatter radar covering 1981–1997, (3) molecular oxygen number density, [O2], solar ultraviolet occultation aboard Solar Maximum Mission. A component, “anomalous oxygen,” allows for appreciable O+ hot atomic contributions at high altitudes applies primarily drag estimation above 500 km. Extensive tables compare our entire NRLMSISE-00, MSISE-90, Jacchia-70 models different altitude bands levels geomagnetic activity. We also explore scientific issues related sets database. Especially noteworthy activity dependence data, with which we study large contribution under combination summer, low activity, latitude, altitude. Under these conditions, except very indeed show significantly higher than does MSISE-90. However, corresponding winter MSIS-class represent noticeable improvement relative over wide range F10.7. Considering two regimes together, achieves an both by incorporating advantages each.
