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

[Toni Klemm]

Hi Rick,

Sadly, that’s not the problem. It occurs in the very first loop already.

However, I just commented out 

;		ncdf->lat_1 = lat_1

which is three lines above the line that doesn’t work, and now the script runs without problems. I still don’t understand why this is happening. Could it be a bug in NCL, some sort of problem with too many variables in an output file?

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.
