Evaluating How Dry Deposition Influences Eastern U.S. Ozone. Aerosols, and Precursors: Mean Contribu

Lead PI: Arlene H. Fiore

Unit Affiliation: Ocean and Climate Physics, Lamont-Doherty Earth Observatory (LDEO)

August 2014 - July 2019
North America ; United States
Project Type: Research

DESCRIPTION: We are investigating mechanistic pathways by which ozone deposits to the terrestrial biosphere using long-term observations, short-term field studies, and a hierarchy of models. We are particularly interested in how these different pathways respond to climate change and variability and the implications for atmospheric composition and air quality.

OUTCOMES: See publications; also raised additional support for a workshop at Lamont on dry deposition: https://atmoschem.ldeo.columbia.edu/ozone-drydep-workshop/
