  1. My previous talk will be available at the ACPD web site. Global chemical transport model study of effects of temperature on isoprene chemistry and emissionsAkinori Ito Vegetation

  2. Isoprene chemistry in a future atmosphere Paul Young, Guang Zeng & John Pyle CentreforAtmospheric Science, Cambridge University, UK iLEAPS Conference, Boulder, January 2006

  3. Increase temp → less PAN → increase O3 PAN → NOx Increase temp → more H2O decrease O3 O3 hν H2O O2+ M O(1D) OH M O(3P) Surface ΔPAN/ ppbv [JAN] The effect of climate: CCEall – Eall Surface ΔO3 / ppbv [JAN] NOT THE WHOLE STORY!

  4. Paul Young et al. Isoprene chemistry in a future atmosphere O3 increase/decrease? Regional… Increasing isoprene in a HIGH (2090) NOx/VOC background VOC-limited regions NOx-limited regions Surface ΔO3 / ppbv: Eall – Eothers[JJA]

  5. Paul Young et al. Isoprene chemistry in a future atmosphere O3 increase/decrease? Regional… Increasing isoprene in a LOW (2000) NOx/VOC background VOC-limited regions NOx-limited regions Isoprene swamps the more NOx-limited atmosphere Surface ΔO3 / ppbv: Eiso – EBASE[JJA]
