AE-E MSIS Neutral Density Data

Published by NASA Space Physics Data Facility (SPDF) Data Services | National Aeronautics and Space Administration | Catalog Last Checked: May 06, 2026 at 06:48 PM | Dataset Last Updated: April 20, 2026
This set of neutral density data was deduced from the mass spectrometer measurements on the Atmosphere Explorer E's Bennett Ion-Mass Spectrometer and Open-Source Neutral Mass Spectrometer. The density numbers (in cm-3) for hydrogen, nitrogen and molecular oxygen were provided by A. Hedin (GSFC, Code 914, now retired). They are related to A. Hedin's atmospheric modelling work (Mass Spectrometer and Incoherent Scatter atmospheric model - MSIS). In addition to density, the record includes also orbital parameters.
