Evaluation of the Impacts of Assimilating the TAMDAR Data on 12/4 km Grid WRF-Based RTFDDA Simulations over the CONUS

Figure 10

(a) Percentage improvements for root mean squared error (RMSE) and (b) correlation improvement for surface pressure, 2 m temperature, 2 m relative humidity, and 10 m wind speed due to the assimilation of the TAMDAR data and the resolution increase. Red bars indicate improvements due to the TAMDAR data for each domain (Domain 1: light red; Domain 2: dark red) while blue bars indicate improvements due to using higher resolution (without TAMDAR data: light blue; with TAMDAR data: dark blue). The abscissa represents the variables while the ordinate represents the improvement. The statistics are averaged over all surface stations and the 6-day (August 1 through August 6) simulation period.
