WAQS 2014 WRF
The WAQS contracted UNC Chapel Hill to simulate 2014 meteorology using the Weather Research Forecast (WRF Version 3.6.1) Advanced Research WRF (WRF-ARW, or WRF) for the 2014 calendar year with a 36 km continental U.S. (CONUS), 12 km western U.S. (WESTUS), and 4 km western state domain (WSD). More information on WAQS 2014 meteorological modeling is provided in the WAQS WRF 2014 MPE Document.
EPA 2014 WRF
EPA contracted UNC Chappel Hill to simulate 2014 meteorology using the Weather Research and Forecasting model (WRF Version 3.8) at a 12-km horizontal resolution for the continental United States (CONUS). The WRF meteorological fields were processed using the Meteorology Chemistry Interface Process (MCIP) to generate Community Multiscale Air Quality (CMAQ)-ready input files. Additionally, the 2014 WRF meteorological fields were processed using the Mesoscale Model Interface Tool (MMIF) to generate input files for dispersion models. EPA WRF 2014 MPE Document.
GEOS-Chem
GEOS-Chem is a global 3-D chemical transport model (CTM) for atmospheric composition driven by meteorological input from the Goddard Earth Observing System (GEOS). 2014 WAQS AQ modeling will use GEOS-Chem output for estimating boundary conditions. EPA's 2014 GEOS-Chem output are available on the IWDW.
