Thanks Wei-kang for preparing this useful information.
These two are netCDF dimensions which in HDF5 (netCDF-4) files are stored as
HDF5 datasets. The above information indicate these HDF5 datasets are taking up
file space although they should not have any actual data. The netCDF library
only needs a specific value in the NAME attribute of these datasets. I, too,
suggest creating your files with the latest version of the netCDF library as it
may improve what kind of create dataset information it passes to the HDF5
library.
