The Mars Global Reference Atmospheric Model (Mars-GRAM) is an atmospheric model based on two General Circulation Models for the lower atmosphere and the thermosphere, stitched together (MGCM and MTGCM). Versions of the model have been adjusted to represent actual data from past missions. Using raw MRO data for each orbit at each latitude, longitude, and altitude while altering distinct atmospheric parameters (e.g., winds, density, temperature, etc.) led to an enhanced understanding of the global atmospheric circulation on Mars. This paper will highlight the most significant advancements of our understanding of the Martian atmosphere from these new data sets from the MRO mission.
