GRIB conversion

[Eric Altshuler]

Danny,

Use 'vi' or some other editor and delete the number at the end of the line. The line should just be:

dtype grib

If there is a number after 'grib', and the grid dimensions are inconsistent with that particular grib type identifier, gribmap and grads may have problems. It is better in most cases not to have any number in the 'dtype grib' line.

Danny,

Check your ctl file for the line 'dtype grib'. If there is a number after 'grib', get rid of it, then try running gribmap again.

Hello All,
   I have coverted my grib file to ctl file, however there is one problem, the index file is not generating......here is what I type and what was responded:
     Â
          grib2ctl.pl Y48659* > Y48659*.ctl     : (everything was fine until I type the next line)
          gribmap -i Y48659*.ctl -0
           Error in the grid specification for GRIB grid type 29/30
           Grid scaling must indicate 2 2.5 x 2.5 grid
            Grid size must be 144 x 73
            Grid must go from 0 to 357.5 and -90 to 90
Â
could someone help me with this if I can get the index file to generate Grads will do the rest......
                                           thanks
                                              DANNY   Â

I use this script instead of 'draw title'.
