Re: [netcdf-java] Grib2Netcdf

Hi Kevin:
There's a bug using relative paths for the input file, which is now fixed. Can you try out version 4.3.3 of toolsUI-4.3.jar ? 

ftp://ftp.unidata.ucar.edu/pub/netcdf-java/v4.3/toolsUI-4.3.jar

Let me know if you see any problems.

Thanks!

Ahhh!  Very good.  Should have known to try the simple solution first.
When trying this file with your recommendation but using v4.3, I'm getting the following error:

    Hi Kevin:

    1) in general, use

    java -Xmx512m -classpath netdfAll-<version>.jar ucar.nc2.dataset.NetcdfDataset 
-in<fileIn>  -out<fileOut>  [-isLargeFile]

    see:

    
http://www.unidata.ucar.edu/software/netcdf-java/reference/Cookbook.html#writeClasssic
2) it appears you are exceeding the 2G limit, so be sure to use -isLargeFile flag 

    3) check to see if the variables are correct, since the tables may
    need updating. Let me know if you see any problems

    Greetings!

    I have been using the utility ucar.nc2.iosp.grib.Grib2Netcdf in
    toolsUI-4.1 successfully to convert High Resolution Rapid Refresh
    (HRRR) GRIB2 files to netcdf-3.

    When trying to use this utility in toolsUI-4.2, I am unable to

    Unfortunately, I can't even find the Grib2Netcdf utility in
    toolsUI-4.3.

    Is this utility no longer available or supported?  Is there
    anything like it in 4.3?  If not, is there a chance that I could
    get this fixed in v4.2?

    I'd be happy to supply the GRIB2 file if people want to test this.

    Many thanks!!
