> Description of problem: Hello,
> 
> I have found an odd issue when trying to view ERA-Interim data both in Grib 
> and NetCDF format. Attached is an image from the IDV when trying to view 
> temperature at 1000 hPa from the ERA-Interim grib data. As you can see half 
> of the earth is masked out, which is incorrect since the data set has global 
> coverage. This data was obtained directly from CISL. As previously discussed 
> with Yuan, there was an issue with the IDV incorrectly reading in the data 
> with the ensemble dimension (see previous support requests). I thought both 
> issues could be fixed if I used CDO to convert the grib data to netCDF using 
> the ECMWF grib table 128. The problem still exists, and even more odd, is 
> that the netCDF data displays differently even when the same exact contouring 
> intervals are used.  Considering this is the same exact data set....there 
> should be no differences. I can upload copies of both the grib file and cdo 
> convereted netCDF if you would like. Thanks for your help.
