[gradsusr] Random Problem Running GrADS in Batch Mode

[Tyler Jankoski]

Hi Aaron,

It seems the problem is random. For example, if 20z works but 21z doesn’t, I’ve tried to go run 20z again and it fails. Sometimes this is the error:

Failed to change directory.
Failed to open file.

*** FATAL ERROR: could not open file: rtma2p5.t21z.2dvaranl_ndfd.grb2 ***

Big problem:
  either rtma2p5.t21z.2dvaranl_ndfd.grb2 is missing or not a grib file
  or wgrib2 is not on your path or wgrib2 is too old
  or can not write to /tmp/g.22076.0.tmp (full disk or permissions).
Open Error:  missing XDEF record 
Open Error:  missing YDEF record 
Open Error:  missing ZDEF record 
Open Error:  missing TDEF record 
Open Error:  missing UNDEF record 
Open Error:  missing DSET record 
Open Error:  missing VARS record 
  The data file was not opened. 


This is the code I am running:

#!/bin/csh -f
set yy=`date -u +%Y`
set mm=`date -u +%m`
set dd=`date -u +%d`
set date=${yy}${mm}${dd}

cd DATA

rm rtma2p5.t21z*

ftp -n ftpprd.ncep.noaa.gov <<ENDFTP2
    user anonymous tjj5091 at psu.edu
    cd pub/data/nccf/com/rtma/para/rtma2p5.${date}
    bin
    get rtma2p5.t21z.2dvaranl_ndfd.grb2
    quit

ENDFTP2

/home/meteo/tjj5091/GrADS/DATA/g2ctl rtma2p5.t21z.2dvaranl_ndfd.grb2 >rtma2p5.t21z.ctl

/usr/global/grads-2.0.1/bin/gribmap -i rtma2p5.t21z.ctl

/usr/global/grads-2.0.1/bin/grads -blc "run t21z.gs"

exit

Thanks,
Tyler
