MOZART-4 is the final version of the global chemical transport model MOZART. The source code is freely available to the community, however it is no longer being developed or supported. Documentation on Downloading and Running MOZART-4 Source Code
The capabilities of MOZART-4, with numerous improvements, are available in CAM-chem and we recommend that it be used instead of MOZART-4.
Several tools are available for processing MOZART-4 output or inputs.
The chemical mechanisms used in MOZART, CAM-chem and WACCM are developed, maintained and updated at NCAR, with collaborations from Forschungszentrum Jülich and the community. The MOZART-4 chemical mechanism and model description are published in Emmons et al. (2010). The MOZART-4 mechanism contains a detailed description of tropospheric inorganic chemistry and of organic species with 3 carbons or less, and a reasonably thorough treatment of isoprene chemistry. Larger alkanes and alkenes, terpenes, and aromatics are also included in the mechanism, albeit with lumping and simplification. New versions of the chemical mechanism are being developed that will treat high hydrocarbons more explicitly.
Chemical Forecasts from MOZART-4 are run each day, providing a 3-day forecast of global tropospheric composition.
