Because the albedo/atmosphere reflect 30% of the incoming solar energy the earth is cooler with that albedo/atmosphere than without. Without an atmosphere the earth would receive 30% more kJ/h becoming a barren rock much like the moon, hot^3 on the lit side, cold^3 on the dark.
This observation is easily confirmed by comparisons with the moon as Nikolov, Kramm suggest and UCLA Diviner mission observes. This refutes the RGHE theory which postulates just the opposite, that the earth sans atmosphere would be a -430 F ball of ice or 288 K w/ - 255 K w/o = 33 C cooler. (Rubbish!)
Because of the non-radiative heat transfer processes of the contiguous participating atmospheric molecules, 396 W/m^2 of BB LWIR upwelling from the surface is not possible.
As I demonstrate in the grand science tradition of performing experiments: https://principia-scientific.org/debunking-the-greenhouse-gas-theory-with-a-boiling-water-pot/
Without the 396 W/m^2 upwelling LWIR there is no net 333 W/m^2 for the GHGs to "trap", "back" radiate or warm anything anywhere.
There is no radiative greenhouse effect and the so-called GHGs do not "warm" the terrestrial surface.
