  • Each graph shows, for each observation time H ([H-3h00,H+3h00[ for long cut-off analysis), daily evolution of brightness temperature CRIS observations monitoring from NPP or NOAA 20 satellites. Daily statistics are provided for 331 infra-red channels and are calculated for clear/cloudy sky or sea/land/sea ice categories. Among these, at most 63 channels are used in NWP data assimilation according to conditions of cloudiness (clear/cloudy) and/or the type of surface (sea/land/sea-ice). These statistics are calculated for clear/cloudy sky or sea/land/sea-ice categories. These categories are :
    • clear sky on sea without ice, land and sea ice
    • cloudy sky on sea without ice, land and sea ice
    On graphs foreach channel, are plotted average and standard-deviation curves of deviation from :
    • first guess before and after bias correction
    • first guess and analysis after bias correction
    Each statistics parameter (average or standard-deviation of first guess before and after bias correction and analysis) is also plotted on synthetic graph for all channels. Bias correction is applied for only CRIS observations which are used in NWP analysis. No bias correction is applied to observations which are blacklisted and corresponding mean and standard deviation curves of deviation from analysis are not calculated. Statistics are presented either for all channels (synthetic shading graphs or 1D graphs), or only for used channels (1D graphs).
