Relative humidity averaging from specific humidity #193

Closed PennyHow closed 1 month ago

From @signehl #188 :

As far as I can see the resampling to hourly averages is the same for all variables, except for wind direction. Have I missed somewhere where rh is treated differently or are rh values also simple hourly averages? I am asking because I think for the average to make physical sense they need to be converted to specific humidity (and perhaps then back to rh?), but I am not sure?

Special averaging needed according to Campbell: https://www.campbellsci.com/blog/averaging-relative-humidity

Relative humidity exception should be raised here in the L3 resampling step:
