[ncl-talk] Question on ncl_filedump on grib files

[Adam Phillips]

Hi Andrew,
NCL doesn't have a built-in table that would fix this issue, but if you can
get your hands on a HRRR table that has been updated to include the newer
entries, you can load it in NCL using an environmental variable. See the
"User-defined GRIB1 parameter tables" section here:
http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclFormatSupport.shtml#GRIB
(I think the instructions would apply to GRIB2 tables as well.)
More information about GRIB issues can be found on that page.
Hope that helps!
Adam
