[Mubashar Dogar]

Dear GraDS users,

I want to use lats4d function for regridding purpose (1.5*1.5 model output
to NCEP 2.5 * 2.5 degree). My model NETCDF have 365 day calendar. I create a
CTL to open my model NETCDF data. Now I have used the following command for
regridding purpose and got the message that CTL file is not opened as
follows. Please suggest me the possible solution for this. ALso please tell
me that time steps in both the model and reference NCEP file (if I just
mention ncep2.5) need to be same or not?
__________________________________________________________________________________
lats4d -i atmos.00060401.ctl -de outfile -func
re(var,144,linear,0,2.5,73,linear,-90,2.5,bl)'
No hardcopy metafile open
All files closed; all defined objects released;
All GrADS attributes have been reinitialized
gaopnc error: nc_open failed to open file atmos.00060401.ctl
read_metadata: gaopnc failed
gadsdf: Couldn't ingest SDF metadata.
lats4d: cannot open file " atmos.00060401.ctl"
lats4d: error creating coards file grads.lats.nc



Thanks,


Mubashar
