Hi all,

When I load in NetCDF files from the 20th century reanalysis dataset
from the NCDC NOMADS TDS, I can read and plot data, but the data values
are not correct. For example, 850 mb temperature grids found in the
air.YYYY.nc files will plot as if their temperatures fall between 430
and 430.7 K, with a default contour interval of .04 K. Similar
unrealistic data ranges/contour levels will appear when other fields in
the 20CR data set are loaded.

The netCDF files look fine, and they plot OK with other tools (I tried
ncview). I suspect there is some issue with how IDV is interpreting the
netcdf file. Note that the "add_offset" value (427.66) in the air.nc
files is suspiciously close to the 430K level that IDV is coming up with
. . .

Any ideas?

Thanks,

--Kevin
