4 Focus Site Data Objectives: Create as complete a record as possible of local conditions, gas, fine particulate mass and component concentrations at source and receptor sites. Make the data available for use in model evaluation. Evaluate the continuous methods used for comparability with existing networks. Responsibility: States, Contractors Deliverables: Verified data in AQS Normalized data on VISTAS site 4

35 Objectives: Focus Sites Routine operation in State Networks Monitors require more attention. Heavier data management load than criteria monitors. SC and NC plan to continue to operate to meet specific state or regional objectives. May need collocated filter analysis. 35

36 Focus project status Data collection phase ended January 1, 2005 Verification and posting of raw data to AQS Normalization Final Reports.. SC and NC have continued some monitoring Supporting data for VISTAS work at ROMA Investigations of PM composition in NC urban areas 36

37 At this point. Continuous monitors provide qualitative information Comparable between sites and methods BUT Filter data is needed to improve correlation between the continuous data and the Standard (filter analysis) 37
