  1. Trace Gases Ge103 Lecture May 24 2005 Yuk Yung x6940; yly@gps.caltech.edu

  2. DictionaryAtmosphere = 1.82x1020 moles = 5.27x1018 Kg1 Tg yr-1 = 109 kg yr-1=3.4 x1010 moles yr-1M = 29

  3. Caltech/JPL 2-D model of the atmosphere January, 60˚ to 70˚ north CH4 Model elevated H2 Current H2 Data shown as * and + are SOLVE balloon measurements for H2 and CH4, respectively

  4. Variations in H2 concentration with time and location

  5. Familiar natural sources of H2 Fires Volcanoes Beasts Rocks

  6. The global atmospheric H2 budget based on concentration records and inventory estimates

  7. Stratospheric water vapor predicted for 2 ppm tropospheric H2 % increase over current Solid lines contour ppmv H2O vapor

  8. CFC Inventor:Thomas Midgely, DuPont, 1930DDT Inventor: Paul Hermann Muller, Swiss chemist1948 Nobel Prize for Medicine
