Atmospheric & Environmental Chemistry Seminar

"Light-Absorbing Impurities in Snow: Origins, Radiative Processes, and Climate Impacts" with Mark Flanner, University of Michigan.

Types of light absorbing impurities found in snow include black carbon, brown carbon, mineral dust, volcanic ash, and snow algae.  Small concentrations of these impurities can have a large impact on the reflectance and melt timing of snow.  This talk will explore the radiative processes that govern snow albedo, the origins and types of key impurities, processes that determine the concentrations of impurities within snow, and the climate impacts of snow darkening as simulated with Earth system models.
