Number of observations
Plots of the number of records assimilated for aircraft reports at CMC in 6-hour periods, divided by format of aircraft report:AIREP/ADS (ICAO), AMDAR (OMM FM42), BUFRS (WMO FM94).

Distribution maps
Distribution maps of observation points assimilated for aircraft reports

Number of observations per time bin
Plots of the number of observations assimilated per time bin (15 min.).

Maps of O-P values
Distribution maps of observations assimilated, after bias correction of aircraft. The color map is based on the ((O-P)/stddev) values.

Zonal plots of O-P values statistics
Zonal plots of O-P values averaged per format of aircraft report:AIREP, ADS, AMDAR, BUFRS

Profils O-P values statistics
Vertical plots of mean, stddev assimilated.

Monthly Means geographic distribution
Plots of the distribution maps of the monthly mean number of observations assimilated per 24-hour period. The maps shows the 10 X 10 degrees distribution of the monthly mean values.

Monthly Number of observations
Trace of the mean number of elements assimilated per 24-hour periods

Monthly Mean Maps of O-P values
Monthly means of O-P for assimilated data. The monthly average is computed for 2 deg. X 2 deg. lat-lon boxes.
