The Mars Climate Modeling Center (MCMC) is NASA’s leading Mars climate modeling team, based at NASA Ames Research Center in Moffett Field, California, within the Planetary Systems Branch (STT) of the Space Science and Astrobiology Division (ST). The MCMC develops the NASA Ames Mars Global Climate Model (MGCM), supporting exploration mission planning and advancing Mars climate science, and openly shares model code, simulation output, and analysis tools with the global research community.
MCMC Products
Most users start with the MGCM visualization tool to explore model output, then use the NAS data portal to download the full dataset and analyze it with CAP. Users who want to run their own simulations can build from the source code.

Model Visualization Tool
The MGCM webserver is an online point-and-click tool for interacting with model output stored on the NAS Data Portal

Model Output
Ready-to-use output from the FV3-based and Legacy MGCM reference simulations, hosted on the NAS Data Portal in netCDF format.

Model Analysis Tools
The Community Analysis Pipeline (CAP): an open-source Python command-line tool for downloading, post-processing, and plotting MGCM output.

Model Code
Source code to run the model yourself: the FV3-based MGCM and the Legacy MGCM.
MCMC Science
The MCMC conducts cutting-edge scientific research on the past and present atmosphere and climate of Mars.
