In the ""Writing encoded data"" section of the xarray doc, it states 

> The encoding argument takes a dictionary with variable names as keys and variable specific encodings as values. These encodings are saved as attributes on the netCDF variables on disk, which allows xarray to faithfully read encoded data back into memory.

I took this to imply that a dataset of type `float64` could be ""compressed"" to `float32` within the NetCDF4 file, and be transparently read back to a `float64` data structure on reading.  Having looked more closely at the NetCDF4 spec, I can't see any way to save this information into the file without adding an arbitrary non-spec attribute.  Would be a cool feature, though.
