MOZART-2
MOZART-2 includes detailed NOx-CH4-NMHC chemistry for the troposphere, with
stratospheric chemistry constrained to climatologies. This version was published in
Horowitz et al., 2003. This version is also known as v2.1 or v2.2.

Source Code
Terms of Use
The source code for MOZART-2 is available to the community, with the following terms:
- The MOZART-2 source code is available to the scientific community to be used solely for educational, research, and not-for-profit purposes.
- Users of MOZART are expected to report any bugs or errors found in the code to the development team (emmons@ucar.edu).
- The MOZART code is released with no warranty on its use.
- Users are asked to not provide the base code to other users outside their home institution, but to direct them to download their own copy, so we can keep an accurate record of the user community and be sure they get update and bug reports directly. If users make any improvements to the code they are also invited to share them with the development team (emmons@ucar.edu) to be considered in future releases.
Computer Requirements and Performance
MOZART-2 currently runs on a variety of platforms. For standard, multi-year simulations at T42 resolution, you will need access to a supercomputer with large amounts of disk space and/or tape storage (~200 GB). Short, or coarse-resolution, simulations or reduced-chemistry versions may be run on Linux workstations. Typically, MOZART is run on computers such as bluevista (IBM multi-processor systems) at NCAR.
More information is available on the Computer Requirements page.
Download
MOZART-2 is available from the NCAR
Community Data Portal. You must first register for the CDP and then register for each version of MOZART desired.
Emissions in MOZART-2
The emissions used in MOZART-2, version 2, are intended to represent the emissions of
the early 1990s. They are based on the inventories of the Emission Database for Global
Atmospheric Research (EDGAR) v2.0, Global Emission Inventory Activity (GEIA), Hao and
Liu [1994], and Müller [1992]. See Horowitz et al. [2003] for details.
