COMPASS-GLM: Coastal Observations, Mechanisms, and Predictions Across Systems and Scales (COMPASS) Great Lakes Modeling (GLM) Pilot Study
This two-year pilot study aims to enhance predictive understanding of freshwater coastal systems especially how they respond to climate warming, changes in land use and cover, and other system changes at scales ranging from
watersheds
to regions. This includes local climate and weather feedbacks that affect wintertime lake effect snows and summertime thunderstorms. Modeling activities will focus on two tasks: regional modeling of the Great Lakes region and watershed modeling in the Portage River watershed.
