John,

Please, find my 2014.nc file at the link below

Please, look at the related discussion on Sourceforge
http://sourceforge.net/p/nco/discussion/9829/thread/a99790ed/
The issue is not still resolved

Charlie also tried h5repack (not successful):
zender@roulee:~$ time ncks -O -4 --cnk_dmn latitude,4 --cnk_dmn
longitude,4 --cnk_dmn time,512 ~/2014.nc ~/2014_ch_ncks.nc

**************
Is it possible to perform chunking programmatically using NetCDF Java library?

Kind regards,
Antonio
