Geonengineering Series: Exploration of Marine Cloud Brightening

In this presentation, Rasch will review some of his Large Eddy Simulation (LES) modeling work on aerosol injections and mixing in the stable high-latitude boundary layer and their impact on mixed-phase clouds, and connect them to recent and proposed observations and field experiments, and to global modeling studies.

Dr. Philip Rasch serves as the Chief Scientist for Climate Science at the Pacific Northwest National Laboratory (PNNL), a Department of Energy Office of Science research laboratory. In his advisory role, he provides leadership and direction to PNNL's Atmospheric Sciences and Global Change (ASGC) Division. The Division conducts research on the long-term impact of human activities on climate and natural resources using a research strategy that starts with measurements and carries that information into models, with a goal of improving the nation's ability to predict climate change.
