I sent your comments for our analysts, who will make data analyses to promote the needed changes... Thanks for attention! Cheers, Eduardo. Quoting Robb Kambic <address@hidden>:
Eduardo, I made the table and debugged the test data. It seems that the GDS section is not standard, especially the number of parellels is way out of the proper range and then the scanning mode value is probably wrong too. According to ECMWF documentation, the max number of parellels is 800. If the data is standard format then I can proceed in debugging. Robb...

Thanks! Cheers, Eduardo. Quoting Robb Kambic <address@hidden>:Eduardo, the easiest way to solve this is to make a sample file available so I can debug the problem. Also, send the table so I can use/add it. Thanks, Robb.... On Tue, 17 Mar 2009, address@hidden wrote:Hi Robb, I would like to thank you for your tips to update the grib-6.0.jar and my grib tables.

How can I proceed to read that file? May you help me with it??? Thanks in advanced! Cheers, Eduardo.
