computed from the latest published values from Sander et al. (2003) , the International Union of Pure and Applied Chemistry (IUPAC; online at ), or from the JPROC files for each species using the algorithm presented by Wild et al. (2000) for a weighted average over each of the seven intervals. This method weights the absorption cross sections and quantum yields at each individual tabulated wavelength value within the wavelength range of each interval with the

over larger areas in a relevant manner. The input meteorological fields were computed with the fifth-generation Pennsylvania State University–National Center for Atmospheric Research (NCAR) Mesoscale Model (MM5) ( Grell et al. 1995 ) using sophisticated algorithms for the representation of cloud microphysics [Reisner scheme, including graupel ( Reisner et al. 1998 )], subgrid cloud parameterization [Kain–Fritsch-2 scheme, including shallow convection ( Kain and Fritsch 1993 ; Kain 2004

simulation. The EM adopted for this study is the Sparse Matrix Operator Kernel Emissions (SMOKE) modeling system ( Houyoux et al. 2000 ) that processes the U.S. Environmental Protection Agency (USEPA) National Emission Inventory (NEI). It computes gridded, temporalized, speciated emissions in the following four data categories: point, area, mobile, and biogenic. A plume rise algorithm partitions stack emissions as a function of height using the NEI stack parameters and time-dependent RCM meteorological
