Mars Global Surveyor: Aerobraking and Observations Support Using a Mars Global Circulation Model

摘要: This is a Final Report for Joint Research Interchange (JRI) between NASA Ames Center and San Jose State University, Department of Meteorology. Using global atmospheric circulation model Mars, the focus this JRI has been to provide support Mars Global Surveyor (MGS) spacecraft aerobraking activities interpretation guidance preliminary observations. The primary applied in investigation high-top version general (MGCM). Comparisons with an designed primarily engineering purposes (Mars-GRAM) also carried out. From suite MGCM simulations, we have assessed plausible spatial temporal variability density at high altitudes (e.g., 70-1 10 km) seasonal dates locations during Phase 1 aerobraking. Diagnostic tools developed analyze fields from these creation climate catalogue database. Throughout I activities, analysis products provided MGS advisory group (AAG). Analyses coupling level thermospheric (MTGCM) assessed. Finally, using quasi-geostrophic dynamical formulation diagnosis breaking planetary (Rossby) waves middle atmosphere Titles papers presented scientific workshops seminars, publication literature are provided.
