[ncl-talk] Error: dimension sizes of left and right hand side do not match

[Rick Brownrigg]

Hi (offline for a moment):

I can not see the problem either. I note that the lines in question are in
a doubly-nested loop. Does this error occur on the very first attempt at
writing a netcdf?  Each time through the loop(s), you are reassigning the
filevariable ncdf -- I'm wondering if the "previous" file is not getting
closed or perhaps the var ncdf retains some stale information?  Perhaps
just before the end of the "if (netCDF1) " statement, place a delete(ncdf),
which somewhat counterintuitively, will close the file.
