Document Summary
Some of the longwave radiation emitted by the earth is absorbed by gases (co2, methane, water vapor, nitrous oxide, cgcs, etc. ) Clouds play a crucial role in the heating of the lower atmosphere. High altitude ice-crystal clouds have albedos of about 50% Energy deficit at the poles because of no direct sunlight. There is a relationship between insolation and daily temp (no surprise) More of a surprise lag time = time of maximum radiation is not time of maximum temp. Right before sunrise = coldest part of day. Simplified surface energy budget (infrared_ - lw (infrared) Time between noon and max temp is called lag time. Net r =+sw (insolation) sw (reflection) + lw. Energy that is stored in water vapor as water. Back and forth transfer between air and surface. Energy flows into and out of the ground surface by conduction. Light energy penetrates surface which transforms into heat energy.
