  1. Testable sensitivities of CTM simulations to meteorological fields Yuhang Wang Georgia Tech

  2. Models • GEOS-CHEM: Used in some comparisons; provides chemical boundary conditions. • Polar MM5 driven regional CTM: Boundary layer sensitivities • MM5 driven RCTM (REAM): spring-summer transition • MM5 and WRF driven REAM: convection and lightning in summer – INTEX-NA

  3. Arctic surface ozone depletion Default ETA MYJ 2.5-order closure Modified ETA (Zeng et al., 2006)

  4. Default ETA Modified ETA

  5. Boundary layer height at the South Pole, 2003 (Wang et al., 2007)

  6. Spring-summer transition:Trop NO2 column retrievals for February-May, 2000 (Choi et al, 2007)

  7. Surface O3 concentrations and afternoon mixing heights February-May, 2000

  8. Summer time convection and lightning MM5: Grell scheme WRF: new K-F scheme (Zhao et al., 2007)

  9. Lightning impact on NO2 column WRF-REAM MM5-REAM

  10. Lightning impact on NO2 at 500 hpa

  11. Convective scavenging of HNO3

  12. Surface O3 simulations
