The WRFv3.0 ARW PS: configuration is based on the WRF-Rapid Refresh (WRF-RR) physics suite and was evaluated by the DTC to assess the impact of vertical resolution near the bottom of the atmosphere on forecasts of atmospheric variables near the land surface. A Contiguous United States (CONUS) domain was employed with a roughly 13-km grid spacing. This configuration is a general application configuration for mid-latitude forecasts.

This task was conducted during the summer of 2008 in support of the implementation of the WRF-RR at the National Centers for Environmental Prediction (NCEP).
