     5Before the WRF Preprocessor System (WPS) runs, input data files need to be in a specific format, so ungrib.exe does is able to parse them. Specifically, files in [http://www.wmo.int/pages/prog/www/WDM/Guides/Guide-binary-2.html GRIB ] format are needed. Furthermore, to WRF be able to run, there are some mandatory fields that must be present in the input files. Some of these are not always available in the driving model data we want to use, such as soil temperature and moisture content. In addition, we need these variables with the frequency that WRF is going to use to update its boundary data (usually 6 hours).
