RPO Monitoring Issues by Marc Pitchford, Ph.D. WRAP Ambient Monitoring & Reporting Forum Co-chair
RPO Monitoring & Data Analysis Activities • Assess data adequacy & supplement if needed • FCIA routine aerosol speciation data for tracking trends (IMPROVE) • Non-FCIA aerosol speciation data for spatial coverage (IMPROVE protocol, Speciation Trends, etc) • Intensive air quality & met. monitoring for model input & validation
RPO Monitoring & Data Analysis Activities (continued) • Data archival & communications • Available databases (IMPROVE, AIRS, NWS) • Approaches (catalog, link, ingest, etc.) • Data validation & documentation
RPO Monitoring & Data Analysis Activities (continued) • Data assessments • Descriptive (statistical & graphical summaries) • Relational (correlation, scatter plots, etc) • Consistency & closure (fine mass, optical, & extinction budgets • Trends (official Haze Rule trends, major aerosol components & precursors, & met.) • Source apportionment (receptor models using composition, spatial/temporal patterns, & trajectories) • Regional air quality model validation (average, best & worst days) • Refinement of natural haze levels
RPO Monitoring & Data Analysis Activities (continued) • Reporting • Routine data reports • Interpretive reports on causes of haze • Format, timing, & frequency of reports to meet RPO, state, & tribal needs
RPO MonitoringIssues of Common Interest • What source apportionment methods should be used? • What role do the RPOs, states, tribes, etc have with respect to reporting data to EPA? • Which trajectory methods & uses of trajectory analysis seem best? • How do we demonstrate progress, show interstate impacts & estimate natural levels?
RPO Monitoring Over-Arching Issues • Opportunities for common &/or compatible • Monitoring systems • Data set & databases • Assessment tools • Requirement for & approaches to conduct cross-RPO-border data assessments
RPO Monitoring Over-Arching Issues • Coordinated requests to mitigate national-scale monitoring deficiencies --- examples • Long-term need for a national network of radar wind profilers to improve modeling performance • Routine quantitative estimates of dust & smoke from outside of the US by a system of satellite remote sensing, dispersion modeling, & surface observations • Methods for continued inter-RPO communications
