These models simulate the emission, transport, chemical transformation, and deposition of hundreds of chemical species across regional to global scales. Three open-source models dominate the research landscape: <strong>GEOS-Chem</strong> from Harvard University, <strong>CMAQ</strong> from the U.S. Environmental Protection Agency, and <strong>CAM-Chem</strong> from the National Center for Atmospheric Research (NCAR). Each serves different scales, research communities, and policy applications.</p>
