The Effect of Humidity on Back Radiation

Continuing the same theme Here is the effect of changing Humidity (both relative and absolute) on the percentage of backradiation compared to upward radiation


Difficult finding a conversion between relative humidity (as measured) and absolute humidity.
the equation used for the above plot was:
abs humidity=1320.65/(273+T)*rh/100*10^(7.4475*(T+273-273.14)/(T+273-39.44))



So It looks as if the effects of cloud cover / temperature should only be made at fixed RH.

Yet more sums to do!
