Hi all:Yes, I think this is the same case as Roy reports. Sloppy GRIB writing which shows up when you do complicated things like CDM tries to do.
We have a workaround, but better wait until we can get 4.3.17 a bit more stale, as Roy had some problems when he tried it.

Hi Kevin: I already ran into this with data from FNMOC, and reported it (is that where your GRIB files are from?). At one point they thought they had a fix, but when i tried it things got mucked up. So this is one they are aware of, and hopefully 4.3.17 will have a fix. At the same time, in our case, I know they didn't really use a different table, and this is sloppy on the providers part, and also is one of the many problems with using external tables. -Roy On May 2, 2013, at 3:12 PM, Kevin Manross <manross@xxxxxxxx> wrote:Greetings! I know there is work being preformed on the GRIB1 in THREDDS, so I do not know if this already being covered or not. I came across the error in the subject line when I expanded my TDS catalog config to cover the extent of my dataset. This caused an Error 500 when trying to view Best Timeseries data via any of the TDS access types/services. I'll spare the gory details unless they are needed. I have isolated this error to a period spanning two months in 1999 (Aug & Sep). After converting the GRIB1 files to netCDF and dumping the netCDF headers, the only variation I see with the Pressure_surface variable is that some use Grib1_TableVersion = 1 and the rest use version 2: fnl_19990814_00_00.cdl: Pressure_surface:Grib1_TableVersion = 2 ; fnl_19990814_12_00.cdl: Pressure_surface:Grib1_TableVersion = 1 ; fnl_19990814_18_00.cdl: Pressure_surface:Grib1_TableVersion = 1 ; fnl_19990815_00_00.cdl: Pressure_surface:Grib1_TableVersion = 2 ; fnl_19990815_06_00.cdl: Pressure_surface:Grib1_TableVersion = 2 ; I would be glad to dig into this further if it provides any help.
