[gradsusr] problem with grib2ctl.pl

[Rowell, Mason D.]

Mubashar,

Are you sure the data is what you expect? Does your grib file have 4 time steps x 30 some days in the month of interest? Or are you positive it is just those for time steps averaged for each day in the month?

Subject: [gradsusr] problem with grib2ctl.pl

Dear GrADS users,

I have downloaded synoptic monthly means analysis data from ECMWF for specific humidity at 1000 pressure level both in netcdf and grib format (This is the same data in grib & netcdf format for three months of 1989). I encountered a bug or some issue in perl script (grib2ctl.pl<http://grib2ctl.pl>) that generates GrADS readable control file for the grib data set. I am attaching grib file and control file made by grib2ctl.pl<http://grib2ctl.pl> as well as index file generated by gribmap. The bug is that synoptic monthly means data have 4 time steps (at 00, 06, 12, & 18) for each month but grib2ctl.pl<http://grib2ctl.pl> makes 4 time steps in each day instead of 4 time step in a month. When I opened the ctl file in GrADS, it display some values and shows rest as all undefined values. I even changed time in ctl manually and generate index again but the problem is yet unresolved. Where is the issue? Does anyone already encountered the same problem. Please see attached files for your satisfaction.
