Corp for Atmospheric Research rkambic@xxxxxxxxxxxxxxxx WWW: http://www.unidata.ucar.edu/ ============================================================================== ---------- Forwarded message ---------- Date: Fri, 23 Jan 2004 10:33:25 -0700 From: Jim Cowie <cowie@xxxxxxxx> To: decoders@xxxxxxxxxxxxxxxx Subject: Sample GFS 1x1 deg cdl Brian, I've attached a sample CDL for the NCEP GFS 1x1 deg grid (AKA grid 3) which we get off the NCEP ftp server. I don't know if it will work with what comes through AWIPS but it is a start. I also have CDLs for the GFS 2.5x2.5 grid (grid 2) and the Eta 211 grid if you want them. The gfs_003.cdl has most or all of the fields defined but many commented out since we don't use them. Also note that though we use gribtonc, we had to make a few changes to it to handle some of the time averaged or time accumulated variables better. gribtonc doesn't handle these very well. (We're hoping that the new gribtonc, currently under development at Unidata, will.) Hope this is usefull to you, -jim -- Jim Cowie NCAR/RAP cowie@xxxxxxxx 303-497-2831 ---------------------------------------------------------------------- HOETH, BRIAN R. (JSC-ZS) (LM) wrote:
Hello, I would be interested in seeing the wrf249.cdl file also. For that matter, I would like to see any cdl files that people have created in their experiences with using gribtonc, other than the default cdl files that come with the package. I am especially interested in finding out if anyone has tried creating AWIPS displayable netCDF files for GFS 1x1 degree data using gribtonc. Example GFS 1x1 degree data from today can be found at: ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/MT.avn_CY.00/RD.20040123/PT.gri d_DF.gr1/ Thanks, Brian Hoeth Spaceflight Meteorology Group Johnson Space Center, Houston, TX Office: 281-483-3246 Operations: 281-483-1051 -----Original Message----- From: owner-decoders@xxxxxxxxxxxxxxxx [mailto:owner-decoders@xxxxxxxxxxxxxxxx]On Behalf Of Robb Kambic Sent: Thursday, January 22, 2004 5:53 PM To: Rorik Peterson Cc: decoders@xxxxxxxxxxxxxxxx; decoders Subject: Re: confusion with record dimension using gribtonc On Thu, 22 Jan 2004, Rorik Peterson wrote:I have been having some problems with the record dimension when decoding Alaska-region GRIB data obtained via ftp from NCEP at: ftp://ftpprd.ncep.noaa.gov/pub/emc/mmb/mmbpll/alaska10.t00z/ The GRIB files available here are updated daily, each one corresponding to a forecast time (0-48 hours). I sequentially process them with 'gribtonc' into a single netCDF file [/user2/ldm/AWIPS]$ perl -e 'foreach(glob "A*"){ `gribtonc wrf249.cdl out.nc < $_`;} However, I always have a complete record of missing data somewhere in the middle. Using today's data, I narrowed it down to when I added the 15-hour forecast file; at which point two records were added instead of one, and the last one was completely empty. Here I decode just one GRIB file: [/user2/ldm/AWIPS]> rm out.nc;gribtonc wrf249.cdl out.nc < AWPREG15.tm00 Then dump the pertient information of what is in there [/user2/ldm/AWIPS]$ ncdump -v valtime_offset out.nc | egrep "record UNLIMITED|valtime_offset =" record = UNLIMITED ; // (2 currently) valtime_offset = 15, 15 ; and then look at the data [/user2/ldm/AWIPS]$ ncks -H -v u -d x,100,100 -d y,100,100 -d level,4,4 out.nc level[4]=500 record[0] level[4]=500 y[100]=986.789 x[100]=986.789 u[540324]=2.17085 record[1] level[4]=500 y[100]=986.789 x[100]=986.789 u[1673253]=-9999 x[100]=986.789 y[100]=986.789Rorik, You already narrowed the problem down to either a bad data product or an error in gribtonc. First test would be to run gribtonc with the -v and -l - flags, ie gribtonc -v -l - ..... Hopefully this should shed some light on the error. Next test would be to use gribdump to check if there is an unusual header in the grib products. In my recent work, I've found a wrong header on only one product in a group of 2000 files. The projection was wrong on the product. ie gribdump -h <gribfile> Can you send me the wrf249.cdl file you are using so I can use it. I downloaded the AWPREG15.tm00 file and will let you know the results. Robb...You can trust me that the entire second record is full of -9999, which is missing_value. Is this a problem with the GRIB data, or gribtonc? All the GRIB files are the same size, more or less, so I don't know where the second set of (missing) data is coming from. Any insight in what to look at next is appreciated. rorik
