VERIFICATION: Scatter plot and mean errors

All pairs of WAM (0-6 hour) and satellite observations have been used.
The number of observations in each 5x5 cm box is shown with colors. Red line : the best fit to data. Green-dash line : one to one relationship.


Errors in 2 dimensions

Average error statistics have been calculated over 100 km bins, to provide enough observations to obtain reliable 2D error estimates
