I have downloaded the diagnostic package-- popdiag_rel_20121121 and changed related roots.
When I run the popdiag.csh, it shows:"no monthly files exist...cannot create climatology
ERROR : unrecognized argument -grid_file
USAGE : za [OPTION]... infilename.nc"
-h|-help (print this help message)
-o outfilename [default: za_infilename.nc]
-time_const (apply averaging to time constant fields)
-A (if outfilename exists, append to it)
-O (if outfilename exists, overwrite it)
-N (no normalization, i.e. compute area sums as opposed to area averages)
-v var1[,var2[...]] variables to process
-x process all variables EXCEPT those specified with -v
-rmask_file filename [default: infilename.nc]
but, the popdiag.csh code include this '-grid_file' choice:
if ($SWIFT == 0) then
187 za -O -time_const -grid_file $gridfile $TAVGFILE
Do you have any advice?
