Re: [ldm-users] fens product at ftp.ncep.noaa.gov

Hi Kevin,
This product (FNMOC Ensemble) uses grib2 tables in NCEP WMO GRIB2 Documentation. You can look for these parameters by product discipline, category and parameter number. For example: Temperature will be in product discipline 0 (Meteorological products), Category 0 and parameter number 0. It is in GRIB2 table 4.2-0-0 See url at: http://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_table4-2-0-0.shtml

The parameter tables which your mentioned "g2varswmo5" and "g2vcrdfnoc0" are for NAWIPS. They are not in the latest GRIB tables in NAWIPS. You can use the information of parameters in grib2 tables in NCEP WMO GRIB2 Documentation to modify your existing table to be substituted instead.
See link at this url for all parameters in grib2:
http://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_table4-1.shtml

Thanks,
Boi

Can you or someone else @ NCEP answer this:

I noticed that this product uses grib2 parameter tables "g2varswmo5" and "g2vcrdfnoc0" . . . do you have any idea where these tables might be? It is not in the latest GRIB tables in NAWIPS 6.2.0. Can the existing g2varswmo4 and gcvcrdwmo0 tables be substituted instead?

Arthur,

The fens files are the FNMOC Ensemble forecast product. The data is available on the NCEP FTP server unmodified from FNMOC. Eventually these datasets will be included in the NAEFS products.
