GEOG 2050 : Exam 2 Notes
Document Summary
Key concepts: transmission, scattering, diffusion, refraction, mirage, reflection, albedo, absorption, rayleigh scattering. Chapter 4 atmosphere and surface energy balances: energy essentials, monday, energy balance at the troposphere, wednesday, energy balance at the earth"s surface, friday. Earth"s energy budget: solar radiation varies, output from sun, distance of earth from sun, daily, seasonally, latitudes, atmosphere functions as a filter, absorbs, gamma rays, x-rays, uv, allows visible to reach earth"s surface, figure 3. 7 and figure 2. 8. Energy pathways: figure 4. 1, ~50% of insolation makes it to the earth"s surface. Insolation (light) is bounced off a surface without being absorbed or scattered: refraction, change in speed and direction of light. Energy essentials: energy pathways, short wave energy from the sun, long wave energy from earth, transmission, passage of energy through atmosphere or water, figure 2. 6 and 4. 1. Insolation input- all radiation received at earth"s surface (direct and indirect: figure 4. 2.
