Number of observations
Plots of the number of profiles assimilated for GBGPS.

Distribution maps
Distribution maps of observation points assimilated for GBGPS data.

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 O-P assimilated, after bias correction of GBGPS. The color map is based on the ((O-P)/stddev) values.

O-P and O-A Statistics
Plots of mean and std of observations minus first guess and observations minus analysis, and plots of the number of observations, after the bias correction and the selection procedure. Means are performed over a 6h period.

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 O-P and O-A Statistics
Shows the monthly means for the last 15 months, of observations minus first guess and observations minus analysis of assimilated data

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.
