The Influence of Close-Range Pollution on Maine's Air Quality During The Peak Ozone Episodes in 1997

During the 1997 ozone smog season, ambient data was collected at three PAMS (Photochemical Assessment Monitoring Station) sites and fifteen ozone monitoring sites within Maine. One of the ozone monitors was located on the Scotia Prince, a passenger ferry that traveled daily between Yarmouth, Nova Scotia and Portland, Maine.

Assessment of the PAMS data, collected during times when Maine's ozone monitoring sites recorded exceedences of the federal ozone standard (0.124 ppm), indicated that ozone levels in Maine are elevated by short-range, anthropogenic (human-made) precursor emissions. Analysis of benzene/toluene, NMOC/NOx, NMOC/NOy ratios, MIR's (Maximum Incremental Reactivity) and other hydrocarbon relationships demonstrates that ozone precursor emissions are transported into and generated within the State of Maine.

Mobile sources are important contributors to these emissions. by Original Author: Michaelsen Clifton

A Proposal to Measure Mercury Deposition and Atmospheric Concentrations in New England: The overall purpose of this proposal is to establish an ambient monitoring network within New England to characterize spatial and temporal patterns of mercury deposition and concentrations in the atmosphere and to provide 1-2 years of data and a final report that describe these patterns and address related hypotheses. The data gathered in this study may provide indications of local versus regional influences and should provide other researchers (including those submitting a related REMAP proposal) with valuable information for developing and validating atmospheric and ecosystem models.

VForEM Seeks Partners in Northeast Forest Trajectory Climatology Project: A small group of regional forest health and air quality organizations are planning a collaborative data analysis project, which involves long-term air trajectory analysis of air quality data at a small number of forested monitoring sites in the Northeastern US (and Eastern Canada). We are actively seeking participation and/or feedback from other groups or individuals that may have common interests. VforEM (Vermont Forest Ecosystem Monitoring, Inc.), the USDA Forest Service, Northeastern Region, CAPITA (Center for Air Pollution Impact and Trend Analysis), VT DEC (Vermont Dept. of Environmental Conservation) and NESCAUM (Northeast States for Coordinated Air Use Management) plan to conduct this project and post results on the neardat website. We are very interested in seeking ideas, advice, participation, feedback (or even supplemental funding support) from others with common interests. Additional details are included in the attached proposal, which contains links providing examples of the participating groups, planned analysis techniques, and key personnel. Additional postings will follow as the project evolves. Please feel free to comment publicly by submitting neardat comments, or privately through E-mail (richp@qtm.anr.state.vt.us) or phone (802) 241-3840.; Submitted by Poirot Rich on 4/18/97 RecID: NEARDAT.Reports.TechReports.RichPoirot3

A Web Based Infrastructure in Support of Regional AQ Management: This is a one-pager outlining what neardat could be about. I kept it intentionally dense so that we can focus on the essence first. It has elements from many e-mail exchanges. You will note that it is like a template. Could be re-used for other regions like MOG :). Major issues are geographic domain ( how could one have it both ways, geofocus as well as broad scale?); pollutants (O3, PM only , what about special issues like mercury?). A companion document could be a much expanded version of this one. Could we get some dialog going here? If nothing else, just say yes, no, BS, whatever. No need to follow Poirot's long prose..; Submitted by Husar Rudolf on 4/11/97 RecID: NEARDAT.Reports.TechReports.RudolfHusar1

Toward More Efficient Transboundary Exchange of Air Quality Data: Meeting presentation by R. Poirot and C. Michaelsen withthe message: "We efficiently exchange air pollution across our border, where it is merged with local source influences, but is too often unobserved, undocumented, and uncontrolled. We need more efficient mechanisms to exchange and merge our collective air quality data!"; Submitted by Poirot Rich on 3/23/97 RecID: NEARDAT.Reports.TechReports.RichPoirot2
