Document Summary

Geob 102 (september 12, 2016) energy balance and. Climate: outline, electromagnetic radiation, energy pathways, the greenhouse effect, global energy budget and surface energy balance. Electromagnetic radiation: radiant energy (electromagnetic waves) is emitted by objects with temperature. > absolute zero (-273 c) (anything with mass: ex. 1 watt of power = 1 joule of energy expended/second (power intensity: phones need 3w. Solar charge would not be sufficient in vancouver to charge laptops because of the cloud cover (less powerful solar charge) Irradiance flux of radiant energy/unit area: curve peaks at lower wavelength for warmer blackbodies (red curve) more radiation emitted/unit area so wavelength is shorter, observed vs. Theoretical solar radiation: absorption of radiation depends on type of wavelength, ozone and water absorb radiation, solar vs. terrestrial radiation diagram. 2: smooth: ideal blackbody emission, jagged: unabsorbed radiation passing through atmosphere, unshaded: radiation absorbed by atmosphere.
