Asymmetric impacts on Mars' polar vortices from an equinoctial Global Dust Storm

The Asymmetric impacts on Mars' polar vortices from an equinoctial Global Dust Storm database is composed of reanalysis products combining past spacecraft observations with a state-of-the-art Mars Global Circulation Model (MGCM), and free-running simulations of the MGCM.

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.
