Webthe radiative transfer equation, which is commonly used for the retrieval of atmospheric quantities (e.g. water vapor) and land surface properties (e.g. soil moisture), is derived based on approximations and simpliﬁcations. More general approaches to solve the radiative transfer equation including multiple scattering are described WebA climate model represents (mathematically of numerically) these exchanges of energy between the Earth system and space. The observed emission to space or Outgoing Longwave Radiation is consistent with an emission temperature T e = 255 K – much colder than Earth’s surface. This is evidence of the greenhouse effect. sphinx livehtml
