Two ways you can do this: 1) If you can do something in NCO, it is probably much simpler to keep doing it in NCO. From Java, you can call Process process = Runtime.getRuntime().exec(cmd); to call an operating system process (but see the detailed examples on the web for how to do this for your operating system), including calling NCO. 2) If I understand the problem, the only way I know of to do this with netcdf-java, is to read the time and other data values and write the .nc files with the individual time values and the data associated with each time (and all the associated dimensions and attributes). That's the nature of working with netcdf-java. (Perhaps someone else will chime in with a simpler method.) P.S. I don't know your reasons for using netcdf-java 4.2. I understand that sometimes projects are, for now, locked into a certain version. But if you can, I encourage you to switch to the latest version (4.6.8). Things are done differently in recent versions of netcdf-java and various bugs have been fixed. You'll probably have to switch to a modern version of Java someday, so, if you can, you might as well switch now so you don't have to rewrite this code later.
