Re: wrf-gribs in ncl?

Hello

I am sure one of the NCL developers will respond more elaborately later
today.

[1] Yes, it is possible to use WRF GRIB files.

[2] *The data values and dimensionality are decoded correctly*.
     
[3] NCL decodes the values but the specific parameter table needed
       to assign a variable name and units is not built-in to NCL. Hence,
       a *warning* message is issued.

Please see the GRIB section of:

http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclFormatSupport.shtml

I believe "center=255" means missing data center identification.

If you know the parameter information, you can input your own table.

Regards

     
There was a recent ncl-talk question regarding WRF GRIB-1
