A -- NORTH AMERICAN RESEARCH STRATEGY FOR TROPOSPHERIC OZONE (NARSTO) CRITICAL REVIEW PAPER ON MONITORING NETWORKS SOL ECA045 POC Otelia Newsome, Contract Specialist, (919)541-3164/Vickie Presnell, Contracting Officer. The Environmental Protection Agency has a requirement for an expert in network monitoring of ozone and ozone precursors to write the NARSTO critical review paper on that subjects. The review paper shall be written suitable for publication in an atmospheric sciences journal. Style and format of the paper should follow the guidelines established for all NARSTO critical review papers. The paper will include an overview of the current state-of-science in network monitoring for ozone and ozone precursors, from the perspective of the measurement methods employed and the potential utility of the date being collected. The methods employed will be reviewed for their robustness and tractability in routine monitoring operations. The site selection, density, and parameters measured will be assessed for the objective of the monitoring network. The emerging PAMS network should receive emphasis in the discussion. The adequacy of the monitoring data will be evaluated for the purposes of establishing ambient concentration trends, for helping to evaluate emissions inventories and verify the impacts of control programs, and for helping to evaluate air quality models and establish their reliability as air quality management tools. The potential for higher-level diagnostic analysis, such as using observation-based models, will be assessed. The critical review shall focus on monitoring network developments beyond those described in the 1991 National Academy of Sciences report on tropospheric ozone, ''Rethinking the Ozone Problem in Urban and Regional Air Pollution.'' The contractor shall participate in two meetings of the combined author panel for all of the NARSTO critical review papers. The draft copy of the report is due 12 months from date of award. The request for quotation will be issued approximately 8/20/96, and quotations will be due approximately 9/3/96. Small-business set-aside. Interested parties may obtain a copy of the RFQ by submitting a written request. No telephonic or faxed requests will be honored (0215)
