Greetings! I do believe you've hit the netCDF-3 Classic Format file size limit. Can you add the flag: -isLargeFile to your command, i.e.: java -classpath netcdfAll-4.6.13.jar ucar.nc2.dataset.NetcdfDataset -in <path> -out <path> -isLargeFile That should allow you to write a 64-bit Offset netCDF-3 format file, which can handle up to 2^63 bytes, or 8 Exabytes.
