GEOG 203 Lecture Notes - Lecture 3: Photosynthetically Active Radiation, Black-Body Radiation, Shortwave Radiation
Document Summary
The at(cid:373)osphere a(cid:374)d solar radiatio(cid:374) a(cid:374)d e(cid:374)ergy (cid:271)ala(cid:374)(cid:272)e at the earth"s surfa(cid:272)e. Electromagnetic spectrum depends on size of wave lengths. Radiation emission: high temperature the more radiation is emitted. Radiation reception: radiation received can be absorbed heated up, reflected albedo, transmitted. What absorbs co2 / what expels it. System that contributes to the climate on earth. Ideolized physical body that absorbs all transmission and transmission from the black body. Earth travels around the sun (1 year) orbit is not fully round eccentricity. Solar constant: average value of this insolation when the earth is at its average distance from the sun. Sun emits ultra violet and x-ray wavelengths. Solar terrestrial energy: see that there are gaps earth there are two big gaps some are absorbed by the atmosphere, co2, water, ghg = this capturing of energy from earth is the ghg effect. Also changes depending on geological time scales 22. 5 deg tilted.
