Seminar

Abstract

In this talk I will present recent work from my group and collaborators that touches on the topics of improving our understanding of sources of air pollutants, and relating specific sources to their impacts on human health through long-term exposure at the urban to national scales. The projects focus on the health impacts of PM_2.5, O₃ and NO₂, and a common theme throughout the projects is the use of remote sensing data to constrain both the inputs to the air quality simulations as well as our estimates of exposure. In particular, I'll present work using NH3 remote sensing from the CrIS instrument to better understand sources of ammonia in the US and Europe. I'll also present results on source apportionment modeling using adjoint sensitivity analysis of air pollution health impacts in G20 countries globally, across different countries in Europe, and in source regions around 14 US cities.
