Comparison between Satellite Water Vapour Observations and Atmospheric Models’ Predictions of the Upper Tropospheric Thermal Radiation
Figure 10
Variation of the amount of low cloud (% of low clouds’ pixels to the sum of clear sky and low clouds) with the brightness temperature at 6.7 μm (BT6.7) wavelength RMSE for various cloud effective emissivity (E) ranges. The determination coefficients on the right in each frame are, respectively, for the relation between the low cloud amount and both the RMSE NCEP/DOE (upper) and RMSE NICAM (lower).
