title: Dataset of "The Roles of Slope Winds, Regolith, and Clouds in Shaping the Martian Water Vapor Column Unveiled With Mars Global Climate Model Simulations."

description: This dataset contains the output of the Mars Global Climate Model simulations. This model has a horizontal resolution of 64 x 32 grid points (longitude x latitude) and a vertical resolution of 32 sigma levels and 20 ground levels.

 

The file "dataset_Kobayashi_2026.tar.gz" includes atmospheric, surface, and subsurface variables in ASCII format.

The file "plev.asc" includes vertical grids of pressure levels.

The file "glev.asc" includes vertical grids of ground levels.

 

The following provides an explanation of variables and their resolutions in the parentheses (nx, ny, nz, nt, nd).

where nx, ny, and nz are the numbers of longitudinal, latitudinal, and vertical grids; nt is the number of data points per sol; and nd is the number of sols.
