GEOS-CHEM

GEOS-Chem enables simulations of atmospheric composition on local to global scales. It can be used off-line as a 3-D chemical transport model driven by assimilated meteorological observations from the Goddard Earth Observing System (GEOS) of the NASA Global Modeling Assimilation Office (GMAO) . It can also be used on-line as a chemical module coupled to weather and climate models. GEOS-Chem is developed and used by hundreds of research groups worldwide as a versatile tool for application to a wide range of atmospheric composition problems. It is open-access and can be downloaded through github. It is also fully supported for use on the Amazon Web Services cloud... GEOS-Chem is a global 3-D model of atmospheric chemistry driven by meteorological input from the Goddard Earth Observing System (GEOS) of the NASA Global Modeling and Assimilation Office. It is applied by research groups around the world to a wide range of atmospheric composition problems. Scientific direction of the model..
