The National Atmospheric Deposition Program (NADP) is a cooperative program of federal, state, tribal and local agencies; educational institutions, private companies and non-governmental groups. NADP provides long-term, high-quality air and precipitation measurements to evaluate atmospheric deposition over space and time. NADP’s 500+ independent sites and four monitoring networks measure acids, nutrients, base

cations, and mercury in precipitation; plus atmospheric concentrations of gaseous ammonia, and gaseous, elemental and particulate mercury. NADP data supports research on multi -pollutant source/ receptor relationships, atmospheric modeling, the potential for deposition effects on terrestrial and aquatic ecosystems, and biogeochemical cycling of pollutants.

About the Meeting

This is the first totally online Technical Meeting and Scientific Symposium in NADP history, and registration is free! Therefore, attendance is anticipated to be historically high and

internationally well attended. The meeting is intended for scientists, resource managers, educators, students, policymakers, and others interested in atmospheric deposition, air quality, and its effects on aquatic and terrestrial ecosystems. NADP data has been used for decades to understand and solve real-world problems impacting people and the planet, including helping to facilitate cleaner water, healthier air quality, more productive fisheries, informed environmental planning, improved air quality and climate forecasting, and responsible

environmental stewardship.

Symposium Theme

“NADP in a Changing World” will focus on adaptation of atmospheric monitoring and modeling methods, emerging contaminants, and new techniques for assessment of human

and ecological effects of atmospheric deposition, to meet the challenges of changing climate, ecosystems, and society. Abstracts and presentations on any topic related to atmospheric deposition are welcomed. The Scientific Symposium will include the following sessions.

October 28: • Changing Physical and Chemical Climates – emissions and

deposition in changing climates

• Advances in Monitoring Reactive Nitrogen, Mercury, andEmerging Contaminants

• Advances in Measurement-Model Fusion for the Future

October 29 :

Effects in Terrestrial and Aquatic Ecosystems

• A Changing Society – urbanization, agriculture, energy, policy• Panel Discussion – regulation(s), environmental effects,

monitoring, engaging industry and the public

October 30 :

Symposium Poster Session – Posters will consist of 4 slidespresented by the authors (5 minutes). Questions will beanswered in the “Chat” function. All topics related toatmospheric science are welcome.
