I will need some clarification. When I do this command ./ncdump -h 'http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/ncep.reanalysis2/pressure/air.2006.nc?air[63:63][0][0:72][0:143],time[63:63],level[0],lat[0:72],lon[0:143]' I see the units attribute for air. It is listed as: air:units = "degK" You reference "...or u wind velocity or v wind velocity or relative humidity or specific humidity or geopotential height." I am not sure what you mean by these because there is no, for example, specific humidity variable that I can see. Can you clarify?
