[gradsusr] BUFR

[Javier Peña]

Dear Grads-Users,

I would like to know how I could generate a ctl for some BURF files.
Following the web page http://www.iges.org/grads/gadoc/bufrformat.html I
have created the following ctl descriptor file for a BUFR file:

DSET ^gdas.adpsfc.t12z.20020203.bufr
title gdas.adpsfc.t12z.20020203
undef 9.999E+20
*  produced by Javier Penha
DTYPE bufr
TVAR yr 4,1 mo 4,2 dy 4,3 hr 4,4 mn 4,5
STID 1,198
XVAR 6,2
YVAR 5,2
TDEF 1 linear 12z03feb2002 1hr
VARS 9
slon 0 6,2 Station longitude
slat 0 5,2 Station latitude
selv 0 7,1 Station elevation
wdir 0 11,001 Wind direction
wspd 0 11,002 Wind speed
temp 0 12,225 Temperature
dewpt 0 12,227 Dew point temperature
mslp 0 10,51 Mean sea level pressure
dp 0 10,61 3-hour pressure change
ENDVARS
but it doesn't work. ¿Does it have some error? When I try to read it with
Grads I obtain the massage:

ga-> sdfopen gdas.adpsfc.t12z.20020203.ctl

gadsdf: Couldn't ingest SDF metadata.
¿Does someone know a script to generate a ctl descriptor file? I'm looking
for some script similar to grib2ctl.pl (used with grib files) but for BUFR
files. ¿Does it exist?

I attach eigther BUFR file and ctl descriptor file.


Thanks in advance for your help.

Javier Peña
