ASA, the blue marble ttp://visibleearth.nasa.gov/view_rec.php?id=2429 Atmosphere: extends upwards ~ 100 km, but ~75% of the mass within 11 km. Functions: Acts as a freshwater distillery. Absorbs cosmic rays and UV radiation. Dust, sea salt, soot, ammonium sulfate, nitrates, organic particles … 0.00001% Gases (99.99999%) Aerosol particles (0.00001%) I. Introduction: Earth’s Atmosphere II. Global Warming – the “Greenhouse Effect” In a greenhouse, UV radiation readily passes through glass. Absorbed by surfaces, it is converted to long-wavelength IR radiation (heat). IR radiation cannot pass through glass easily and is trapped, heating up the greenhouse.
