Land-atmosphere interactions are central to understanding current and future trends in weather and climate. Regional-scale surface fluxes are the quantities often required for model input and/or validation. Quantifying the relationship between local and large regional-scale fluxes and their connection to surface properties and atmospheric boundary layer (ABL)-flow regime has been the motivation for numerous field campaigns and remains an unsolved problem.
In this seminar, after reviewing regional climate projections and their problems related to surface‑atmosphere interactions, Prof. Fochesatto will describe observational platforms and newly developed methodologies that would enable connecting surface turbulent fluxes with ABL parameters. He will discuss multiscale turbulent fluxes experiments carried out in the most vulnerable ecosystems on earth. And, he will introduce new empirical approximations of multiscale turbulent fluxes. To conclude, Prof. Fochesatto will share his research strategy for the next generation of experiments integrating observations and modeling approaches.
Prof. Fochesatto's research interests focus on land-atmosphere interactions in complex heterogeneous surfaces and canopies characterizing high latitude environments. His group developed experiments to improve understanding of land-atmosphere coupling processes from micro-meteorological to atmospheric boundary layer scales.
Prof. Fochesatto has extensive research experience on determination of surface fluxes of heat, moisture, and carbon as tracers of surface-atmosphere interaction in Arctic Tundra, Alaskan Boreal Forest, and high latitude agro-ecosystems.
