That seems consistent with the other uses of defined_by, all of the sort ocean_mixed_layer_thckness_defined_by_Y. I prefer this to 'as a function of', for reasons Jim stated.

I find that conclusion a reach, both because Y is only ambiguously a coordinate, and 'having bounds' has a slightly tricky meaning in this context.
Since area_fraction_defined_by_solar_zenith_angle_within_bounds is clearer on its own, I like it better. But if y'all feel happier without the last bound-y bit, OK then, the definition will serve to bring that forward.
