报告简介:
After a brief introduction into surface - atmosphere interaction research using micrometeorological techniques, I will present recent findings from long-term water and carbon flux measurements made in the Inuvialuit Settlement Region in the western Canadian Arctic where I work closely with Indigenous communities to guide the research. The Inuvialuit Settlement Region is characterized by increasing natural and anthropogenic pressures including rapid atmospheric warming, weather extremes (e.g., droughts and/or heatwaves), tall shrub and beaver encroachment, wildfires, and economic development. Understanding the resulting changes in surface - atmosphere interactions and thus local (e.g., subsistence activities), regional (e.g., weather) and global ecosystem services (e.g., carbon storage) requires tight integration of Western science and traditional knowledge.
报告人简介:
Dr. Sonnentag is Associate Professor and former Canada Research Chair in Atmospheric Biogeosciences in High Latitudes (2014-2024) at the Université de Montréal in Montréal, QC, Canada. His research aims to understand changes in surface-atmosphere interactions in response to increasing natural and anthropogenic pressures, with a focus on the Northwest Territories. Sonnentag uses micrometeorological measurements, and remote sensing and modelling techniques to study changes in Arctic-boreal ecosystem composition, structure, function and services. Sonnentag is involved in a range of research initiatives and programs including AmeriFlux/FLUXNET, Can-Peat, NSERC CREATE LEAP and PermafrostNet.
