WRF-CHEM Version 3.8.1 Users Guide


The WRF-Chem User's Guide is designed to provide the reader with information specific to the chemistry part of the WRF model and its potential applications. It will provide the user a description of the WRF-Chem model and discuss specific issues related to generating a forecast that includes chemical constituents beyond what is typically used by today's meteorological forecast models. For additional information regarding the WRF model, the reader is referred to the WRF model User's Guide ( Presently, the WRF-Chem model is now released as part of the Weather Research and Forecasting (WRF) modeling package. And due to this dependence upon WRF, it is assumed that anyone choosing to use WRF-Chem is very familiar with the set-up and use of the basic WRF model. It would be best for new WRF users to first gain training and experience in editing, compiling, configuring, and using WRF before venturing into the more advanced realm of setting up and running the WRF-Chem model--Page 3.
