The Community Multiscale Air Quality (CMAQ) modeling system Version 5.1 (CMAQv5.1) is scheduled for release in September 2015. To facilitate community contributions to this model release, a beta version was created and made available to external collaborators/developers on April 10, 2015. There are several new features included in this release (). This Beta-version will undergo extensive application and evaluation over the next few months, which may lead to additional changes before the final release this fall.
The release notes describe how to obtain a copy of CMAQv5.1 beta.
CMAQv5.0.2 DDM Patch Release
A patch for the CMAQv5.0.2 DDM codes is now available. The aerosol sensitivity code was updated to ensure stability and robustness for fine scale model applications. Propagating sensitivity through some ISORROPIA cases were found to be unstable under certain conditions. These cases were replaced with solutions for a more simple ion system.
Other minor changes were made to how small numbers are handled by the sensitivity code. Sensitivity to activity coefficients was also found to function improperly and was disabled. Finally, updates to sensitivity of minor ions in aqueous chemistry were also disable to further ensure stable model solutions.
CMAQ | | | | | | | |
The Community Multiscale Air Quality (CMAQ) Modeling System combines current knowledge in atmospheric science and air quality modeling with multi-processor computing techniques in an open-source framework to deliver fast, technically sound estimates of ozone, particulates, toxics, and acid deposition.
