Tiziana,
Since I not familar with the avn (grid 3, 65160 point) model in
particular I can't give a direct answer but I will the give procedure on
how to get the correct CDL. If the LAPS cdl file works by all means use
it. But I would check the output using ncdump to make sure all the fields
are being populated. NetCDF allocates the space before the input is
actually processed so reserving variable space without using it is wasted.
At this time, the status of the LAPS gribtonc code is not known. It's
possible they have modified the code so Unidata's gribtonc will not work
with their cdl.
Another approach would be to use the would be to use the closest fit avn
cdl file from the tar files and then modify the x and y parameters or lat
and lon parameters, using avn-1.25x1.25 as a template then it would look
like this at the bottom of the file. ie
At top:
lat = 181 ; // latitude
lon = 360 ;
At bottom:
lon = -30, -29, -28 ....
lat = -90.0, -89.0 -88.0 ....
I would run the newing created cdl from the command line to check out your
progress.
% gribtonc -vl - avn-1.0x1.0.cdl test.nc < avn.input
Hopes this helps,
Robb...
