NADP is an internationally recognized program that provides long-term, high-quality precipitation chemistry measurements in order to evaluate temporal and spatial trends in wet deposition. Three networks make up the NADP: two that measure acids, nutrients, and base cations in precipitation: NTN (National Trends Network, weekly samples) and AIRMoN (Atmospheric Integrated Research Monitoring Network, daily samples), and one that measures mercury in precipitation, MDN (Mercury Deposition Network). Complementing these wet deposition measurements, the Clean Air Status and Trends Network (CASTNet) measures air pollutant concentrations and computes dry deposition. Data from NADP and CASTNet support research on pollutant source/receptor relationships, the potential for deposition effects on terrestrial and aquatic ecosystems, and biogeochemical cycling of pollutants. NADP’s mission also includes outreach to the general public

About the Meeting: The meeting is intended for scientists, policy-makers, regional managers and students interested in air quality, atmospheric deposition and its effects on natural and cultural resources. NADP subcommittee meetings, open to all, convene September 10. The Scientific Symposium will be on Tuesday and Wednesday, September 11-12. This will include a poster session and reception on Tuesday evening. An optional research/educational (and fun!) field trip is planned for Thursday to spectacular Rocky Mountain National Park. Abstracts for oral and poster presentations are invited on all aspects of atmospheric deposition research and policy, and especially on the following topics:

• Measurement of wet and dry deposition components not currently monitored by national networks
• Importance of deposition in areas not well monitored, such as cities and roadways
• Deposition in the Rocky Mountains and alpine environments; patterns, impacts, and critical loads
• Climate change impacts deposition. Are there greenhouse gas mitigation strategies that will work?

Abstract Submission: Please e-mail titles and abstracts (up to 500 words - one page limit), including author(s) name(s), affiliation(s), mailing address(es), telephone number(s), e-mail address(es), and presentation preference (oral or poster) to Kathy Douglas at Kathy@sws.uiuc.edu  Due Friday, July 20, 2007.

Field Trip: This is a full-day trip with the bus leaving the hotel at 8:00 am and returning around 5:00 pm. A box lunch will be provided. In addition to several other stops, we will be taking a guided hike along the semi-flat Ute Trail at 11,500 feet (approximately 1.0 miles round trip). The group will be joined by NPS interpreters/natural resource staff members and researchers who will give informative talks along the way. Please dress in layers and be prepared for all types of weather (including snow). And don’t forget your sunscreen.
