amv Data Included in the Variational Analysis

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

Distribution maps
Distribution maps of observation points assimilated for AMV 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 of O-P assimilated, after bias correction of AMV layers. The color map is based on the ((O-P)/stddev) values.

O-P and O-A Statistics
Plots, per layers, 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.

Zonal plots of O-P values statistics
Zonal plots of O-P values averaged per satellite

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.
