AB: Air pollution assessments typically focus on the "current" pollutant of concern, often shifting through categories (e.g., acid gases, particles, ozone) with an attendant change in spatial focus (e.g., neighborhood, urban, regional, global). Despite the lag between emerging scientific evidence and incorporation into policies, the most recent shift in air program management aligns well with our understanding that many of the processes controlling origin, transformation fate and removal of pollutants are well integrated across varying scales of space, time, chemical composition and environmental media. The combination of air pollution complexity and multiplicity of effects demands more comprehensive characterizations through a multi-faceted collaborative assessment effort. This presentation explores key observational and simulation linkages toward optimizing the broader characterization capability across space and ground based systems.
