Each graph shows, for each observation time H ([H-3h00,H+3h00[ for long cut-off
analysis), daily evolution of brightness temperature SSMI/S, GMI, AMSR2 and MWRI
observations monitoring from DMSP F17, DMSP F18, GPM, GCOM-W1 and FY3-D
Daily statistics are calculated for each SSMI/S channel and clear/cloudy sky
categories on sea without ice.
On these graphs are plotted average and standard-deviation curves of deviation
from :
- first guess before and after bias correction
- first guess and analysis after bias correction
Bias correction is applied for only SSMIS/GMI/AMSR2 and MWRI 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.
