Hi all,
I am currently dealing with an issue with GRIB2 data from The Australian BOM
- They offer GRIB2 data for forecast satellite imagery. The issue though is
that the 2 different satellite images both use the same variable name of
BRTEMP (see below):
wgrib2 IDY25001.APS3.syncld.slv.2022120612.120.surface.grb2
1:0:d=2022120612:BRTEMP:no_level:120 hour fcst:GMS 5 VISSR (GMS-5) 10.79 um
2:171088:d=2022120612:BRTEMP:no_level:120 hour fcst:MTSAT-2 IMAGER/MTSAT-2
6.80 um
How do I deal with this when creating a control file with g2ctl? Is this
data unusable with GRADS because of this situation? If I just run g2ctl with
no config, it produces a control file as follows:
dtype grib2
options template
ydef 512 linear -54.902344 0.117187
xdef 427 linear 95.009765 0.175781
tdef 5 linear 00Z10dec2022 3hr
zdef 1 linear 1 1
vars 1
BRTEMP 0,-1 0,5,7 ** no_level Brightness Temperature [K]
ENDVARS
Then when I try and display that data I get all undefined data.
Cheers, Mike
