GCTM: Global Chemistry Transport Modeling
There are several models being developed and used in ACD for global chemical transport modeling.
The Model for OZone and Related chemical Tracers (MOZART) is a global 3-D chemical transport model driven by offline meteorological fields, that has been developed at NCAR, the Max-Planck-Institute for Meteorology, and NOAA/GFDL. MOZART-3 includes tropospheric and stratospheric chemistry and MOZART-4 is particularly suited for tropospheric and air quality studies.
CAM-Chem is a version of the NCAR Community Atmosphere Model (CAM) coupled with the MOZART (or other) chemical scheme. There are two versions of CAM-Chem are being developed, one with fully coupled chemistry and climate, and one that reads analyzed meteorological fields, such as NCEP. CAM is a component of the NCAR Community Climate System Model (CCSM).
The Whole-Atmosphere Community Climate Model (WACCM) includes the MOZART-3 (stratospheric) chemical mechanism and is particularly suited for studies from the upper troposphere through the mesosphere.
