Short unit names
nicer on plots - e.g. 'm^2*s/deg' instead of 'meter_pow_2_sec_per_deg'.
Should we also change display_name:
items:
0: Energy density <Wave energy density> (meter pow 2 sec per deg)
While we are at it... should we also provide a version with units using math expression?

Yes maybe - I guess the difference would mostly be on degrees. Note that typesetting of units in LaTeX should not be standard math mode (italics) https://tex.stackexchange.com/questions/509939/problem-with-units-in-math-mode
I was thinking about units like these: https://github.com/DHI/mikeio/blob/70949a4eae059a338398a5baee03d9a284e333a3/mikeio/eum.py#L884
which could be translated to (ignore the italics)
$$ g / m^2 / d $$
which is ambiguous since it could be interpreted either as
$$ \frac{\frac{g}{m^2}}{d} = g m^{-2} d $$
or
$$ \frac{g}{m^2 d} = g m^{-2} d^{-1}$$
where the second version is most likely the correct one.
@jsmariegaard should we merge this, or do you have anything else to add?
@ecomodeller you can merge 👍
