Asatellite viewing a surface location under cloud-free conditions measures a 12 µm radiance of 6.2 wm-2 µm-1 sr1 . (a) compute it’s brightness temperature. (b) compute the actual temperature of the surface assuming the atmosphere is completely transparent of 12 µm and the surface has an emissivity of 0.9 at this wavelength. (c) is the ratio of brightness temperature to actual temperature equal to the emissivity of the surface?
