Each graph shows, for each observation time H ([H3h00,H+3h00[ for long cutoff
analysis), daily evolution of brightness temperature GEOSTATIONARY RADIANCES
observations monitoring from METEOSAT, HIMAWARI and GOES geostationary satellites.
Daily statistics are calculated for each GEOSTATIONARY RADIANCES channel and
clear/cloudy sky or sea/land categories.
On these graphs are plotted average and standarddeviation curves of deviation from :
 first guess before and after bias correction
 first guess and analysis after bias correction
Bias correction is applied for only GEOSTATIONARY RADIANCES 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.
