Christina WilliamsonResearch Scientist, NOAA Chemical Sciences Laboratory, will present “Climate Relevant Impacts of Aerosol Nucleation in the Remote Atmosphere.”

Aerosol nucleation, the process by which solid or liquid particles form from the gas-phase in the atmosphere, impacts climate when these particles grow to sizes where they alter the properties of clouds or interact with radiation. This work uses data from the NASA Atmospheric Tomography Mission, a set of pole-to-pole flights profiling the remote atmosphere, to understand where in the remote atmosphere nucleation is occurring, and what impacts this has on climate. We focus on the impact of nucleation in the tropical upper troposphere on boundary layer clouds, and on newly formed particles in the lowermost stratosphere as potential global-scale signature of aviation emissions.

The event will take place on Google Meets
