Dry Adiabiatic Lapse Rate The top curve is the surface infra-red radiation (- - -) filtered through the atmospheric transmission characteristics. Below 10 microns the water vapour is the main absorber, above 12 microns it is CO 2 and H 2 O. At 9.6 microns there is an ozone (O 3 ) absorption band. The temperature at the extremes of wavelength is rather that of the emitting gas at more or less the tropopause (see below) - 218K. The simple temperature balance equation above gave an expected effective temperature for the earth of 246K (T e spherical). What we actually see is 218K and a modulated 288K, averaging out to what you would get from a 246K Planck curve. Temperature profile of the earth's atmosphere Note that the structure is defined as a number of layers (-spheres) separated by -pauses which are defined as the inflection points - thus the tropopause defines the top of the troposphere and is where the temperature gradient turns over from negative to positive. The troposphere is heated
