[ncl-talk] problem reading grib2 file (ncl v6.5.0)

[Athanasios Karagiannidis]

Dear Rick

Thanx for your immediate reply. I opened the file with the 6.0.0 version, but failed with the 6.5.0 version. I have to state though, that they are installed in different Linux machines.
There should be a problem with Linux machine that hosts the 6.5.0 version, since other weird errors came up also (like segmentation faults when reading a file!). It seems that I should talk to my system admin...
I also thank you for the conversion to NetCDF. However, I should be able to read the grib files, as I have to do that on a daily basis.

Hi,

I was able to read this file just fine with NCL 6.5.0.  Are you using an older version of NCL?  In any case, I've converted the file to NetCDF. I'll send that to you in a subsequent attachment.

Dear all

I am using ncl v6.5.0 in a Linux environment.

I am trying to read some grib2 files, without success. I copied the related error below. I have to note here that in a previous version of ncl (6.0.0) the file was read with no problem.

I attach the file for your convenience.



ncl 0> sf=addfile("gfs.2018100400.t00z.0p25.2018100502.grb","r")

fatal:GdsCEGrid: Invalid grid detected

fatal:NclGRIB2: Couldn't handle dimension information returned by grid decoding

fatal:NclGRIB2: Deleting reference to parameter because of decoding error



Kind regards
