    238243As stated before, a step of the WRF Preprocessor System (WPS), called geogrid, is not included in the WRF4G workflow. Thus, the user must deal with it by hand, or using another tool, such as [http://www.wrfportal.org/ WRF portal]. Geogrid does the task of extracting the fixed fields (orography, land use data, etc.) that WRF needs to run at a given resolution and region. In the WRF4G framework, the output of geogrid is known as the "domain" of an experiment. Inside the original WRF4G tarball there are two example domains, Santander_50km and wrfuc, located in `$HOME/WRF4G/repository/domains`. Here, we are going to see how a new one can be added. It's important to note that there exists an [http://www.mmm.ucar.edu/wrf/OnLineTutorial/index.htm excellent on-line tutorial] for running WPS and WRF by hand. Users of WRF4G are encouraged to work through this tutorial before start running with WRF4G itself. This framework is intended to make life much easier for WRF users, but knowledge about WRF itself is needed to deal with common errors and issues, and to carry on a correct interpretation of the results.
