Robb- I wrote earlier to the mailing list regarding hurricane Isabel data that I was converting from GRIB to NetCDF. Apparently, the GRIB data has a time range, which gribtocdl doesn't handle that well. As a result, the conversion from grib => netcdf produced an extra record frame with blank data. To solve this, I edited the cdl output from gribtocdl and modified valtime_offset to be equal to 1 rather than 2 in the dimension section and changed it from 0, $time to $time in the data section. However, this does not seem to work with my new dataset. It shows a valtime_offset of 1 but the record dimension shows 2. An example grib data file is attached.
Lori, The problem is the data in the file has more than one reference time, ie reftime = 41592, 41592, 41591 datetime "1996-09-29 00:00:00Z", "1996-09-29 00:00:00Z", "1996-09-28 23:00:00Z" ; gribtonc was written for model data with one reference time with offsets to forecast times. I believe it was the PRECIP parameter with the 1996-09-28 23:00:00Z reference time. If you remove the PRECIP data then you can get the results that you want. Robb...
