[ncl-talk] large ESMF regrid intermediate files

[Katelyn Watson]

I have a couple of NCL scripts I have been using to regrid data and am
having trouble with a new dataset, because the intermediate files appear to
be too big to write.  I was able to subset and run the scripts, but I would
prefer not to.  I found some mention of this issue back in the ncl-talk
archives (https://www.ncl.ucar.edu/Support/talk_archives/2014/1840.html)
and was curious if there were updates since then.

I have tried including the line below, but still got the same error.  I
would include the script and files, but the files are not particularly
small.

setfileoption("nc","format","NetCDF4")

Thanks,
Katelyn
