WRF/WPS 2016

Introduction

The WRF Preprocessing System (WPS) is a new software introduced in WRF V2.2, to replace the existing WRF SI. The static fields and grid domains are specified in the first program, geogrid (analagous to the SI gridgen program). The external analysis and forecast data are decoded from the Grib format with the ungrib program in WPS (similar to the grib_prep program in SI). The final program in the WPS suite is the metgrid program, which horizontally interpolates the data from ungrib (similar to the hinterp program in SI). The vertical interpolation has been moved to the real program under WRF.

In Version 3, WPS is the only pre-processing software supported.
