It is possible to create a merged netCDF-4 files and use it for mosaic dataset input.

Step-by-step guide

  1. Subset variable and store it as a small netCDF-4 file.
  2. Use NCO ncecat to merge nc4 files.
  3. Use python to adjust time dimension.


File names for small files should have a pattern like t001.nc, t002.nc, ..., t365.nc to merge in sequence.
