So, explain how CO2 is able to re-radiate absorbed energy toward the surface, when
its collisional decay rate in the troposphere is more than 10x faster than its radiative decay.
Not exact matches
The stratosphere cools with more CO2 because up there, the radiative
decay rate is faster than the
collisional decay.
The CO2
collisional vs. radiative
decay rates are about 15 microseconds and 0.43 seconds, respectively, at 220 K and 1 atm., for a ratio of about 29,000 (Curtis & Goody (1956) Thermal Radiation in the Upper Atmosphere Proc.
