Impact/Purpose:
The goal of this research is to develop and test appropriate chemical and physical mechanisms for use in EPA's Models-3 chemical/transport models. These models will be addressing issues of tropospheric photochemistry, fine particles, toxic and semi-volatile substances, and acid deposition. As such, scientifically credible mechanisms for atmospheric gas- and aqueous-phase chemistry as well as heterogeneous chemistry, applicable to the particular pollutant regimes must be included in Models-3.
Description:
Meteorological data are important in many of the processes simulated in the Community Multi-Scale Air Quality (CMAQ) model and the Models-3 framework. The first meteorology model that has been selected and evaluated with CMAQ is the Fifth-Generation Pennsylvania State University/National Center for Atmospheric Research (NCAR) Mesoscale Model (MM5). All software in the Penn State/NCAR mesoscale modeling system has been dedicated to the public domain and is presently used for both research and operational purposes at many organizations worldwide. Other meteorological models are being considered for compatibility with CMAQ but are not available at this time.
This document is a basic overview of MM5 and its relationship with CMAQ and Models-3. Some general information is provided to help the user get started with MM5 in preparation for Models-3 and CMAQ,, and it is meant to supplement NCAR's official documentation on MM5.
