- GEOS-Chem Model - A global three-dimensional model of atmospheric composition driven by assimilated meteorological observations from the Goddard Earth Observing System (GEOS).
- GO CART model - Simulates major tropospheric aerosol components, including sulfate, dust, black carbon (BC), organic carbon (OC), and sea-salt aerosols.
- IMAGE - Atmospheric Chemistry - Calculates the concentrations of the most important greenhouse gases and other reactive gases.
- RIAM-CFORS (Chemical weather FORecast System) - A global chemical transformation and transport model.
- Unified Chemistry Transport Model (UCTM) Model - Designed and developed to study both tropospheric and stratospheric photochemistry.
