From Robert.Mulloy at calpine.com Tue Nov 12 16:32:10 2024 From: Robert.Mulloy at calpine.com (Robert Mulloy) Date: Tue, 12 Nov 2024 21:32:10 +0000 Subject: [gradsusr] g2grb help Message-ID: Hi Grads User List I'm looking for some help with g2grb. I am trying to save 500mb height anomaly fields to a grib file and I've tried the following g2grb commands and all of the files are empty. The script runs w/out issue; the output from the runs are below. Am I looking for the wrong variable? The input files are 500mb fields with one field being GP500mb and the other being Z500mb. When I run d smth9(GP500mb.1 - Z500mb.2) I get a series of height anomaly maps for all 21 timesteps. I'm using the default template.grb2 template. define anomaly=(GP500mb.1 - Z500mb.2) g2grb anomaly GP_Var.grib d=2024102300:GP:500 mb:24 hour fcst g2grb anomaly HGT_Var.grib d=2024102300:HGT:500 mb:24 hour fcst For GP ga-> g2grb anomaly GP_Var.grib d=2024102300:GP:500 mb:6 hour fcst dlon=0.25 nx = 1441 lon0 = 0 Y is varying Lat = -90 to 90 Y = 1 to 721 dlat=0.25 ny = 721 lat0 = -90 new grads found undef=-999000000.000000 making template file ! /home/rm11714/wgrib2 /Archive/grib/template.grb2 -d 1 -lola 0:1441:0.25 -90:721:0.25 GP_Var.grib.template grib 1:0:d=2009080100:var discipline=0 master_table=2 parmcat=255 parm=255:no_level:-2147483647 missing fcst: opening fwrite GP_Var.grib.tmp going to display anomaly result is Wrote 1038961 of 1038961 elements to GP_Var.grib.tmp as Sequential Big_Endian metadata = 1:0:d=2024102300:GP:500 mb:6 hour fcst: ! /home/rm11714/wgrib2 GP_Var.grib.template -import_ieee GP_Var.grib.tmp -set_metadata GP_Var.grib.inv -undefine_val -999000000.000000 -grib_out GP_Var.grib 1:0:d=2024102300:GP:500 mb:6 hour fcst: !rm GP_Var.grib.tmp GP_Var.grib.inv !rm GP_Var.grib.template For HGT ga-> g2grb anomaly HGT_Var.grib d=2024102300:HGT:500 mb:6 hour fcst dlon=0.25 nx = 1441 lon0 = 0 Y is varying Lat = -90 to 90 Y = 1 to 721 dlat=0.25 ny = 721 lat0 = -90 new grads found undef=-999000000.000000 making template file ! /home/rm11714/wgrib2 /Archive/grib/template.grb2 -d 1 -lola 0:1441:0.25 -90:721:0.25 HGT_Var.grib.template grib 1:0:d=2009080100:var discipline=0 master_table=2 parmcat=255 parm=255:no_level:-2147483647 missing fcst: opening fwrite HGT_Var.grib.tmp going to display anomaly result is Wrote 1038961 of 1038961 elements to HGT_Var.grib.tmp as Sequential Big_Endian metadata = 1:0:d=2024102300:HGT:500 mb:6 hour fcst: ! /home/rm11714/wgrib2 HGT_Var.grib.template -import_ieee HGT_Var.grib.tmp -set_metadata HGT_Var.grib.inv -undefine_val -999000000.000000 -grib_out HGT_Var.grib 1:0:d=2024102300:HGT:500 mb:6 hour fcst: !rm HGT_Var.grib.tmp HGT_Var.grib.inv !rm HGT_Var.grib.template Thanks for the look Rob COMPANY CONFIDENTIALITY NOTICE: The information in this e-mail may be confidential and/or privileged and protected by work product immunity or other legal rules.

URL: From wesley.ebisuzaki at noaa.gov Fri Nov 22 10:27:08 2024 From: wesley.ebisuzaki at noaa.gov (Wesley Ebisuzaki - NOAA Federal) Date: Fri, 22 Nov 2024 10:27:08 -0500 Subject: [gradsusr] g2grb help In-Reply-To: References: Message-ID: Robert, A bug was introduced into wgrib2's import_ieee routine when it was parallelized to make it faster. This broke g2grb.gs which uses -import_ieee. A fix for intel/amd cpus is to edit g2grb.gs old: 'set fwrite -sq -be ' filetmp new: 'set fwrite -sq -le ' filetmp Change -import_ieee to -import_bin in two lines. It's not portable to big_endian machines but it is faster. The -import_ieee fix will be in the next release.
