Mars Global Reference Atmospheric Model (Mars-GRAM) Current and Future Upgrades

The Global Reference Atmospheric Model (GRAM) is one of the most widely used engineering models of the atmosphere. From early concept to operations, engineering missions often rely on GRAM for atmospheric estimates that are used in simulations for performance predictions. NASA’s Science Mission Directorate (SMD) funds development and upgrades to the GRAMs which are performed by personnel at NASA Marshall Space Flight Center and NASA Langley Research Center. This presentation will provide details regarding recent Mars-GRAM upgrades and potential future upgrades that would result from incorporating Mars L1 mission observational data products.
