gancsetup error:

[Matias Mendez]

Hello GrADS users,

I got 3-h NARR data (u-wind and v-wind at 10m, air temperature at 2m,
mean sea level pressure) for the period 1979-2003, from this link:

ftp://ftp.cdc.noaa.gov/Datasets/NARR/monolevel/

I constructed ddf files to open data. It worked well, I could open,
display and analize winds and temperature data. But when I tried to
display mean SLP data I got this error message:

ga-> d slp
Notice:  Automatic Grid Interpolation Taking Place
gancsetup error: Variable slp not in netcdf file
Data Request Error:  Error for variable 'slp'
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = slp

What does this mean?, how can I fix it?.


This is its DDF:

dset /home2/PROCLIMA/NARR/d-MSLP/prmsl.2003.nc

I'm using GrADS v1.9b4. I'll thank you so much your help.
