Solar radiation and the global energy budget

This chapter describes how radiation from the sun enters the atmosphere and reaches the surface. The effects on solar radiation of absorbing gases and the scattering effects of aerosols are examined. Then terrestrial longwave (infrared) radiation is discussed in order to explain the radiation balance. At the surface, an energy balance exists due to the additional transfers of sensible and latent heat to the atmosphere. The effects of heating on surface temperature characteristics are then presented.
