MARS GLOBAL REFERENCE ATMOSPHERIC
MODEL (Mars-GRAM 2005)
Description:
Mars Global Reference Atmospheric Model (Mars-GRAM) is an
engineering-level atmospheric model, widely used for diverse
mission applications. Applications include systems design,
performance analysis, and operations planning for
aerobraking, entry descent and landing, and aerocapture.
From 0-80 km altitude, Mars-GRAM is based on NASA Ames Mars
General Circulation Model (MGCM), while above 80 km it is
based on Mars Thermospheric General Circulation Model (MTGCM).
Mars-GRAM and MGCM use surface topography from Mars Global
Surveyor Mars Orbiting Laser Altimeter (MOLA), with
altitudes referenced to the MOLA constant potential surface
(areoid).
