"Classic" NMC Global Analyses - Comments

It is worth noting two points about this data. The temperature sent by the NMC is virtual temperature, this was corrected to temperature when the tapes were generated. However, the NMC sets RH to zero above 300 MB, therefore the temperature at those levels is unchanged from the data sent by the NMC.

Missing data:
This dataset presented interesting problems in that there were numerous times for which data was missing. This made using the dataset somewhat problematical over long periods of time. Thus a decision was made to fill the missing days with data from a similar dataset. The dataset chosen was the ECMWF WCRPII dataset, information on that dataset is also available from this catalog.
