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