________________________________________WPS Purpose of the WPS l Prepares input to ARW for real-data simulations – – Defines simulation domain and nested domains. computes latigude, longitude, map scale factors, Coriolis parameters for ever grid point. Interpolates time-invariant terrestrial data to simulation grids (e. g. terrain height and soil type). Interpolates time-varying meteorological fields from another model onto simulation domains. 2 __________________________Community Modeling and Analysis System

________________________________________WPS Programs l geogrid – l ungrib – – l Define size/location of model domains and interpolate static terrestrial fields to simulation grids. Extract meteorological fields from Gri. B files. 'Vtables' are used to select which variables are used from each model Gri. B file. You can copy and modify these files for your own Gri. B data sets. metgrid – Horizontally interpolate meteorological fields to simulation grids. 6 __________________________Community Modeling and Analysis System
