  7. GEOS-4 GEOS-3 Fraction Opt. Dep. Cloud Optical Depth in GEOS-5 • GEOS-4: high clouds have very low optical depth - hence too little OH production by photolysis (plots from J. Logan compare GEOS-4 to GEOS-3 in July 2003 and 2001) • GEOS-5: July 2006 cloud properties - • Cloud fractions different! • Optical depths larger than GEOS-4

At runtime one selects one or more packages to run and in case of ambiguity,which package provides a specific input to radiation. Each package exposes its constituents to the GCM and requests specific “services” for each.

  18. Summary • Our objective for chemistry studies with GEOS-5 and the MAP CTM Framework are: • To support applications in weather, climate, and data assimilation modes, with various of chemistry/aerosol packages. • To support both “online” or “offline” studies within a single code base, allowing for direct comparison and validation of offline methodology. • To provide forcing from GMAO simulations and analyses tailored to CTMF applications. • To support external “Met” forcing and Chem components in CTMF
