Atmospheric Aerosol, Air Quality and Climate Change

Prof. Douglas R. Worsnop

15:00, 3 September, 2014

LAPC Meeting Room, Institute of Atmospheric Physics

Abstract:

Atmospheric aerosol continues to contribute the largest uncertainty to predicting future global warming and climate change according to the latest IPCC 2013 report. At the same time, correlation of aerosol loading and human mortality remains the strongest evidence for anthropogenic air pollution health effects. In the 21stcentury, increasing aerosol loading in Asia is degrading air quality even as decreasing emissions in North America and Europe are leading to measurable improvements in air quality. These issues will be discussed in terms of fundamental aerosol chemistry and microphysics – and their measurement and observation.
