Spacecraft observations of column dust optical depth and temperature profiles from the Mars Climate Sounder (MCS) on the Mars Reconnaissance Orbiter (MRO) and temperature profiles from the Atmospheric Chemistry Suite (ACS) on the ExoMars Trace Gas Orbiter (TGO) are combined with an MGCM used at the Open University. The standard database includes key variables such as surface pressure, atmospheric temperature, radiative heating rates, wind speeds, column dust optical depth, and potential vorticity.
Further details on this dataset can be found in the Polar_vortices_GDS_impacts_dataset_reference.pdf document.
