Below one can find the direct "raw" data sets such as send in by the
various modelers. Only the following slight modifications are made in
order to put all data sets in exactly the same format:
sets A,C,D,F are all interpolated to "full" levels: z=20,60....2900m
sets B,E,G, are all interpolated to "half" levels: z=0 ,40....2880m
