Measurement-Model Fusion for Global Total Atmospheric Deposition Initiative (2021-2023)
Jeff Geddes is the principal investigator on this grant funded by Environment and Climate Change Canada. This project is aimed at combining ground measurements, satellite observations, and chemical transport modeling to predict global atmospheric deposition of nitrogen- and sulfur-containing compounds. The deposition of these compounds impact ecosystem productivity and biodiversity, but global maps of deposition are challenged by a lack of high-quality ground-based observations. We aim to show how combining satellite observations and models can help overcome this, especially in regions of the world that lack infrastructure for dense air quality monitoring.
