### Is your feature request related to a problem? ~~Currently, Xarray's GroupBy operations are limited to single variables. Grouping by multiple coordinates (e.g., `time.year` and `time.season`) requires creating a new...

Refactor tests to use floating points for data (not `np.ones` or `np.zeros`)

4

There are some tests (e.g., `TestDepartures`) that use `np.ones` or `np.zeros`, so the output of these operations won't produce outputs the discern correctness of behavior. Instead, we should have tests...
