Missing values in newer version of CDO
Added by Rachel James almost 11 years ago
Hello,
I'm having trouble reading some netCDF files in CDO version 1.5.9.
I have been working with the files on a server which uses CDO version 1.4.6, and now I have been trying to work with them on a new server which uses CDO version 1.5.9. When I try to read the files using a cdo command (e.g. cdo info, cdo output) only missing values ("nan") are displayed. I don't think there is a problem with the data, because I can read it using ncdump, IDL, and GrADS. And I can still run cdo commands on the old server.
The data in question are winds from NCEP/NCAR reanalysis. I have been running cdo commands on other netCDF files (including other variables from NCEP) without any problems.
I would be very grateful for any help with this.
Many thanks,
Rachel

Hi,
Can you please upload:
1) a sample of your original data (must be < 50MB or a link to download the data), and
2) the output of "cdo -V"
Cheers,
J

Hi,
I can reproduce the problem with CDO 1.5.9. However, this problem seems to be fixed in the latest version CDO v1.6.x
Cheers,
