You can either use lossy compression again, or store your data as float instead of double to reduce the output file size.

So, as you can see, the `swh` variable was promoted from a `short` to a `double` which is why your dataset has increased in size. The current version of `where` inserts NaNs in place of fill values but these cannot be represented as a `short`.

In the next version of xarray (0.10) we will have an improved version of where that will help with some of this. @fmaussion also has some good suggestions.
