Hi,

I don't know. Look here:
http://nco.sourceforge.net/nco.html#SEC17

The issue with the days should probably work, if your data has the right time stamp in each file. Just test it.

Good luck,
Heiner

HI Cellyn,

you can use the NCO library with its command ncrcat
or you use the CDO (climate data operators) with its command "cdo cat"

Both packages are available on the internet and are very useful when working with netcdf-files.

Heiner
