All,We have several users who still require grib1 format data, and I've got cnvgrib working just fine. However, the way that cnvgrib reads its input data, you can't redirect stdin to it. What I mean is something like
cnvgrib -21 grib2file grib1file works great, but something like cat grib2file | cnvgrib -21 - grib1file does not.Does anyone have a good way of piping grib2 data into a converter to write out grib1 data from within pqact.conf? I guess the other alternative would be to wait for the status messages to come in and use those to trigger a batch conversion, but with the split feeds, it's not certain that the status message means that the data is complete, since the other feeds may still be coming in.
Thanks for any ideas. Pete Steve Chiswell wrote:
CONDUIT data users, On Tuesday Sep 25, NCEP will begin producing 10 additional fields in the GEFS ensemble data output in support of TIGGE. These fields are:- Specific humidity at 1000, 925, 850, 700, 500, 300, 250, & 200 mb- Potential vorticity at 320K theta - Dewpoint temperature at 2 m AGL These parameters will be added to the files being inserted as: data2/TIGGE/gepXX.tHHz.pgrb2cfFF The current size of these files is ~300KB, and will increase to ~800KB per perturbation (20) and forecast time (65) for a total of 650MB per run time (4x per day). After taking in to account feedback received from my message on Sep 13, 2007 regarding replacement of existing GRIB1 data sets with GRIB2 versions, a two week transition period between changes will be scheduled as follows: DATE 10/02/2007 Remove existing RUC GRIB1 data (GRIB2 data already being sent) Add NAM awipak and grbgrd GRIB2 data files 10/16/2007 Remove NAM awipak and grbgrd GRIB1 data files Add NAM awip3d GRIB2 data files 10/30/2007 Remove NAM awip3d GRIB1 data files I will be updating the CONDUIT data examples on the web page with additional patterns to reflect these changes.
