Hello Simon, Since both files are netCDF4 compressed that means they use chunking. My wild guess is that different chunking defaults cause the observed change in dumping time. You can see the chunk sizes employed with ncdump -s or ncks --hdn, and you can play with the chunk sizes/policy with either. Charlie -- Charlie Zender, Earth System Sci. & Computer Sci.
