Grib file Template !!

[Eric Altshuler]

Dear Kiran Salunke,

You need to have the following in your dset line:

dset ^T254_IND_%f2h.grb

Use %f2 instead of %h2 because the time information in the file names is given by forecast hour (2 or 3 digits). You should also have all the options on one line:

options yrev template

And your tdef line should have 21 instead of 20 in it, because there are 21 time levels (including the 00 hr forecast).

Then run gribmap on the .ctl file after you make these changes.

Hello everybody,
      I have a data (6hrly) in grib format. I would like to make it in
.ctl format using grib2ctl.pl script.It's a five day forecast (120 hr) files.

   The following *.ctl working for one day i.e (06hr,12hr,18hr) it's not
running for 24hr because it is next day.

The files are as follow:

T254_IND_00h.grb   T254_IND_36h.grb
T254_IND_06h.grb   T254_IND_42h.grb
T254_IND_12h.grb  T254_IND_48h.grb
T254_IND_18h.grb  T254_IND_54h.grb
T254_IND_24h.grb  .
T254_IND_30h.grb  .
                  . T254_IND_120h.grb

----------------------------------------
I am writing in this way:
---------------------------------------------
dset ^T254_IND_%h2h.grb
index ^fcs.idx
undef 9.999E+20
