6 years ago Please try opening the grib2 file in ToolsUI, following the same approach shown here for NetCDF file: https://www.youtube.com/watch?v=w-Df4Np7tLA
If you can't plot it in ToolsUI, it won't work with nctoolbox.
I am trying to open a .grb2 file using ncload and I am getting the following error -

2018-05-16 18:51:53,335 [main] ERROR ucar.nc2.grib.grib2.Grib2DataReader - Grib2DataSection.jpeg2000Unpacking: bit rate too small nb =13 for filewnd10m.cdas1.201305.grb2
Requested bitrate is too small.
This same error message repeats a few hundred times and is only one part of the error.
The second part of error is Error using assignin Invalid variable name "u-component_of_wind_height_above_ground" in ASSIGNIN.
Error in ncload (line 19) assignin('base',vstr,nc.data(vstr));
I am guessing the second part of the error is because of the hyphen in the variable name but I am not sure if there is a way for me to fix.
I would like to either open this file or be able to convert it to .nc format. Any help greatly appreciated. Thanks!
