Introduction:
We Present A Summary Of The Gem-Mars Database And Tools Developed For Interpolating Vertical
Profiles To Any Local Geometry. We Also Introduce A
Publicly Data Service On Vespa For Easy Access.
Gem-Mars:
Gem-Mars Is A General Circulation Model For
The Atmosphere Of Mars With Online Atmospheric
Chemistry. The Model Is Operated On A Grid With A
Horizontal Resolution Of 4°X4° And With 103 Vertical
Levels Reaching From The Surface To ~150 Km. It Calculates Atmospheric Heating And Cooling Rates By
Solar And Ir Radiation Through Atmospheric Co And
Dust And Ice Particles And Solves The Primitive Equations Of Atmospheric Dynamics. Geophysical Boundary Conditions Are Taken From Observations. Physical
Parameterizations In The Model Include An Interactive
Condensation/Surface Pressure Cycle, A Fully Interactive Water Cycle Including Cloud Radiative Feedbacks,
A Thermal Soil Model Including Subsurface Ice, Interactive Dust Lifting Schemes For Saltation And Dust Devils, Turbulent Transport In The Atmospheric Surface
Layer And Convective Transport Inside The Planetary
