 v5 == postprocessors in WRF4G == Similar to preprocessor, WRF4G postprocessor is an executable script that can be written in any programming language, provided it does accept one argument, which is one WRF raw file. We usually use a modified version of p_interp to interpolate to filter out unnecessary variables and interpolate to pressure levels. Note that users with large storage resources may not be interested in using a postprocessor. In order to create a postprocessor, it has to be located in the wrf4g_files/bin directory of the specific experiment. Post-processors are included under the $WRF4G_DEPLOYMENT_DIR/repository/apps/postprocessor/ directory.
