grib2ctl.pl problem

[Litta AJ]

Hi,

 

I have got half hourly output files for 24 hours by running wrf post processor(WPP). The following are the examples..

WRFPRS_d01.000_00, WRFPRS_d01.000_30, WRFPRS_d01.000_30WRFPRS_d01.001_30, ....., WRFPRS_d01.023_00, WRFPRS_d01.023_30, WRFPRS_d01.024_00. 



I have created .ctl files by using grib2ctl.pl

 

For that, i have made a concatenated file by cat command. then grib2ctl.pl and gribmap 



cat WRFPRS_d01.000_00, WRFPRS_d01.000_30, ....., WRFPRS_d01.023_30, WRFPRS_d01.024_00 > wrfprs_d01

grib2ctl.pl -verf wrfprs_d01 > wrfprs_d01.ctl

gribmap -i wrfprs_d01.ctl

 

But i am not getting the half hourly output. It is producing hourly output. I have changed the time definition of wrfprs_d01.ctl file 

from

tdef 25 linear 00Z11may2009 1hr

to

tdef 49 linear 00Z11may2009 30 mn

 

Then also i didn't get the output... How can we plot the half hourly outputs through grads using grib2ctl.pl?

Please help 



with best regards,

Litta
