Comparison between Satellite Water Vapour Observations and Atmospheric Models’ Predictions of the Upper Tropospheric Thermal Radiation

Table 2

RMSE (root mean square error) between the observation data and the NCEP/DOE, then the NICAM UTBT (TB6.7) and UTRH during the year 2006. NCEP represents the NCEP/DOE data.
