What is the spatial pattern of NA according to OTAG measures? What is the size of NA areas and how is it determined? What are the OTAG measures of non-attainment (NA)? Transport Questions What are the nonattainment regions where transport of regional ozone is significant? For how many days do airmasses carrying ozone and/or ozone precursors tend to persist within the OTAG domain? To what degree is NA in a given area is influenced by transport from outside? What is the role of vertical transport? What are the conditions (space, time, meteorology) conducive for transport? What is the distance (seasonal, directional) over which emissions influence NA sites? What is the magnitude of regional ozone outside NA areas? Source Questions Does an emission of ozone contribute to ambient ozone levels? What is ozone's source and function? Are current ozone models consistent with ambient and lab data? Can ambient data yield information/verification of precursor emission rates? Do precursor concentration pattern correspond to respective emission data? What is the spatio-temporal pattern of precursors, NOx, VOC, PAMS-species?
