GGR112H5 Lecture Notes - Lecture 5: Rayleigh Scattering, Solar Irradiance, Wave Power
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 reflected or absorbed, energy penetrates atmosphere at right angle to the. In addition to the albedo of clouds, aerosols in the. Desert regions do not have much reflection, receive high atmospheric column insolation yearly. Rayleigh scattering why the sky is blue* Short wave energy gets reflected 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.
