Lecture 5 091312 Artic sea ice thin 10 100 feet of ice 0 Shrunk over the month Antarctic ice stays cold year round 10000 feet of ice Visible wavelength radiation is incoming solar radiation Selective absorption by certain gases outgoing radiation from Earth is not perfectly smooth thus Earth is not a perfect blackbody 0 Greenhouse gases absorb outgoing IR radiation only at specific wavelengths thus blocking the escape of some long wave energy heat I Where its absorbing radiation and overlapping with existing greenhouse gases Sun is closest to a blackbody absorbs all radiation and emits all radiation smoothly and continuously 0 Bad blackbodv re ects radiation 0 Example moon albedo of 07 and is fairly white Red longest wavelength weakest Orange Yellow Green Blue Indigo Violet shortest wavelength strongest O Easier to see green light than red light 0 The colder the body the more energy the body is emitting longer wavelength Height of the curve is proportional to the amount of total energy CH4 and C02 absorb in some regions where H20 do not C02 absorbs long wavelengths H20 works with microwaves Multiple greenhouse effects gwp global warming potential 0 Infrared Most common wavelength of radiation emitted from earth OOOOO Wien s Law a description of the relationship between temperature and most abundant wavelength of emission Stratosphere ozone a special case 0 Protects us from uv radiation otherwise we d all be more mole like greenhouse gas 0 03 absorption 39 UV A 39 UV B O BAS 1980s stratosphere ozone decreased dramatically 0 Ozone molecule 3 oxygen atoms stable continually produced if there is sunlight sunlight dependent and continually destroyed light dependent 39 02 O I O3 39 03 hV I 02 O 0 1950s CFC s air conditioning cleaners non polar grease O Takes a year for molecules to get to the bottom of stratosphere stable 0 UV radiation in stratosphere 39 CFChVFCl 0 Cold temperatures 0 Stable 0 Dark I polar stratospheric clouds high 3040km Antarcticaarctic 0 Do we have stratospheric depletion in the arctic 0 Conditions are not quite right good amount of deplete few percent over certain years less stabledoes not mix with air around it and in northern hemisphere volcano eruption increases depletion 0 Ozone affects your lungs strong oxidant sickly sweet smell 0 Northern hemisphere gets more sun southern hemisphere gets less sun Summertime in northern hemisphere increased solar input SZA1 increase length of day more solar input for a longer period of time Lecture 6 September 18 2012 Jet stream planes y wind moves from west to east
