This would be a good plot to help us see the overall structure. As confirmed in this Pangeo discussion thread, this is not currently possible with xarray:

However, it may be possible with scipy. Here are some relevant threads that I found:

The mode is not yet a standard function in the scipy statistics. This is currently being worked on:

https://github.com/scipy/scipy/issues/14895

However, it looks like one can define a custom function for the mode, which could help us accomplish this.

This doesn't seem to be possible without considerable fuss. Closing for now. We'll go with the mean value, which is a little weird, but it produces okay results.
