[gradsusr] Reanalysis from ECMWF

[Tobias Lundberg]

Hej Marie,

Nu vet jag ju inte riktigt vad du vill använda datan till. Men varför
laddar du inte hem den som netcdf istället. Om du använder sdfopen i grads
så får du i stort sett all info du behöver. Alternativt kan du använda cdo
för att få ännu bättre info om vad som finns i filen.

Mvh,

  Hello I am a meteorology student from Sweden and I am doing my bachelor
thesis.

I am a beginner in using GrADS and I have a problem when I work with ECMWF
reanalysis (ERA-Interim). I download them in GRIB-format (1.5x15
resolution) and then tries to decode them with *wgrib. *I don´t get any
information about the lon and lat, but since I have the resolution from the
download, that shouldn´t be any problem.

Then I create the .ctl file and tries to run the script. Then an error code
shows for every value saying: *GRIB grid size does not match
descriptor*and I do not get any matches. I have defined XDEF as XDEF
240 linear 0.0
1.5 and YDEF as YDEF 121 linear -90.0 1.5.

The strange thing is that it does not work on my computers but he same .ctl
works at my friend´s computer and I do not have any problem using
grib2-files.

Kind Regards
Marie Staerk
