Each graph shows, for each observation time H ([H-3h00,H+3h00[ for long cut-off
analysis), daily evolution of brightness temperature and returned relative humidity
from ATMS and MWTS2 observations monitoring respectively from NPP/NOAA 20/NOAA 21
and FY-3D satellites. Daily statistics are calculated for each ATMS or MWTS2 channel
and clear/cloudy sky or sea/land/sea ice categories and each producer center
(Eumetsat, Lannion EARS or DBNet).
These categories are :
- clear sky on sea without ice, land and sea ice
- cloudy sky on sea without ice, land and sea 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 ATMS/MWTS2 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.
