Lecture notes es10 January 30, 2008 Atm CO2 measurements. NOAA-CMDL Around 100 sites at remote marine locations Long term increase Seasonal cycle N-S Gradient Southern Hemisphere is lagging behind by a year. Energy comes from: 1) Solar radiation (343 w/m squared)-----------99.98% of total 2) Core of Earth 0.06 w/m squared 3) Tides 0.006 w/m squared Intensity of radiation on Earth’s surface is much stronger in the equator, around pole, language of the energy cycle: The Electromagnetic Spectrum Greenhouse gases= H20, N20 (nitrate), CH4 (methane), C02, 03. Greenhouse effect: Radiation at specific wavelengths excite C02 into higher energy states= energy is “absorbed” by the C02 molecules.

Unformatted text preview: Characteristic Absorption/ Transmission for different gases 0-15 Mm. Infrared Radiation=Radiation traits coming up from the Earth, the more absorption we have. Incoming Solar Radiation= 51% Absorbed to surface. 21% (45% of that absorbed from the atmosphere, ice often gets lost to space, but during the process air gets lost to space but during the process air gets trapped, and eventually becomes greenhouse gases, enhancing the greenhouse effect. Humans add a little, warm up surface of the planet.) IR from surface, 23% latent heat flux, 7% sensible heat flux....
