Hi everyone! I have some trouble figuring out the following question: If oxygen, nitrogen and ozone did not absorb UV radiation, what would you expect the temperature profile in the atmosphere to look like between the surface and top of the atmosphere? Specify the temperatures at Tropopause, Stratopause and Mesopause. My guess would be that the surface would become hotter, however, I am not sure about the rest... I would appreciate any help!
