Figure 5.6. 19.35 GHz vs. 37 GHz scatterplot of the simulated TBs in the Turkish CRDdatabase (top left) and of the measured TBs in the SSM/I – SSMISmeasurements database (top right) – in both case, over land only.Figure 5.7 represents in a better way than previous case as for the the consistencyof the simulations with the measurements. However, in Figure 5.6, 50.3 GHz is lesssensitive to surface characteristics than the lower window frequencies.Figure 5.7. 37 GHz vs. 50.3 GHz scatterplot of SSMIS simulated and measured TBs.Surface emissivity does not impact significantly on the upwelling TBs at these highwindow frequencies. However, exceptions are only in thin cloud presence with very lowprecipitation. On the other hand, the overall consistency for simulations database showsthe ice contents that are simulated rather properly by the UW-NMS model, where anappropriate ice scattering parameterizations is considered.18
Figure 5.8. 91.66 GHz vs. 150 GHz scatterplot of SSMIS simulated and measured TBs.Figure 5.9 presents intense water vapor line absorption frequencies at 183.31 GHz.Herein, the surface emissivity impact is negligible, but overall simulation consistencyshows the ice contents, which are simulated by the UW-NMS model. Accordingly,appropriate ice scattering parameterizations are adopted especially at higher cloudportions.Figure 5.9. 183.31±3 GHz vs. 183.31±7 GHz scatterplot of SSMIS simulated andmeasured TBs.5.2. Applications of the CDRD Algorithm5.2.1. Comparisions of Radar and RetrievalIn Figure 5.12a, scatter diagrams are obtained by considerations of 1x1 and 3x3resolution rain rate retrivals versus radar values, respectively. According to 45 degree line,the overall regression line indicates overestimation results with a very significant variability19
