Clean air and clean water are essential for life on Earth. In the United States, the National Atmospheric Deposition Program (NADP)--a cooperative effort between federal, state, tribal and local governmental agencies, educational institutions, private companies, and non-governmental agencies--has been monitoring precipitation chemistry at hundreds of sites across the country for decades. This extensive network has been crucial in improving our understanding of the causes of acid precipitation and its effects on ecosystems across the country (http://nadp.sws.uiuc.edu/NADP/).

Each year, scientific advances on spatial patterns, temporal trends, and ecosystem effects of atmospheric deposition (the deposition of materials to the earth's surface) are presented at the NADP technical meeting. This year, Jenna Rindy and Dr. Alexandra Ponette-González were invited to participate in the "Urban Air Quality and Deposition" session at the 2017 San Diego meeting.

Jenna Rindy won 1st place in the graduate student poster competition for her poster "Atmospheric Elemental Carbon (EC): Deposition to Oak Trees and Litterfall Flux to Soil in an Urban Area". Congratulations Jenna!
