Re: writing latitude to the file

Hi Alexander,
Dave A. is correct that you are attempting to write a bigger file than the original classic format NetCDF allows. You may be able to use the
"largefile" option and still keep the file as NetCDF3. That would be:

setfileoption("nc","Format","LargeFile") (also aliased as "64BitOffset")

Otherwise you will need to move to NetCDF4 classic model:

setfileoption("nc","Format","NetCDF4Classic")

This call needs to be made prior to opening the output file.
