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

Figure 4

(a) Percentage improvements for root mean squared error (RMSE) and (b) correlation improvement for temperature, mixing ratio, relative humidity, and wind speed due to the resolution increase (without TAMDAR data: red bars; with TAMDAR data: blue bars). The abscissa represents the variables while the ordinate represents the improvement. The statistics are averaged over all sounding locations, vertical levels, and the 6-day (August 1 through August 6) simulation period.
