Document Summary
Ggr112 lecture 5 atmosphere & surface. Flow of energy as it leaves the sun into earth"s system. Net radiation = energy in energy out. 1 w = 1 joule (energy) per second. Net radiation includes shortwave (insolation) and long wave energy (thermal) Energy pathways and principles: shortwave energy from sun (insolation, long wave (thermal) energy within earth system. Transmission: passing of energy through atmosphere or water, energy that gets relected or absorbed. Direct insolation: energy penetrates atmosphere at right angle to the sun. In addition to the albedo of clouds, aerosols in the atmospheric column. Desert regions do not have much relection, receive high insolation yearly. Rayleigh scattering why the sky is blue* Short wave energy gets relected and scattered by aerosols and gases: they are smaller than the wavelength of blue light. Also part of the reason why we get nice sunsets on earth. Reason we see rainbows, and the sun that is not visible directly.
