Document Summary
February 13: - transmission, scattering, diffusion, refraction, mirage, reflection, albedo, absorption, Insolation input all radiation received at earth"s surface direct and indirect: figure 4. 2 i. ii. red/orange colors mean a lot of energy is coming in: maximums in western us, australia, Northern and southern africa, middle of south america just outside the. Blue/green means less energy is coming in some is near the tropics! Means we"re losing energy near there: energy pathways a. Pinatubo reduced the average global temperature by 0. 5 degrees c: pollutants i. Absorption is also happening heating in the upper part of the atmosphere. -31: atmospheric absorption (by clouds, gasses, and dust) 21, surface 45% energy coming in, longwave, atmospheric heat input 21, convective transfer 23, greenhouse effect 14, direct heat loss to space 8% In water, sun"s rays can penetrate up to 130 feet. & forests and cloudy regions have less: global net radiation, figure 2. 11/or moodle.
