1. Evaluation and improvement of the representation of snow cover in the Canadian Regional Climate models CRCM4 and CRCM5 over northern Québec The main objective of the proposed project is to evaluate and improve the representation of snow cover within the Canadian Regional Climate Model MRCC4 and MRCC5 in northern Quebec. Research activities include an assessment of the characterization of important snow cover processes in MRCC4 and MRCC5 in northern Quebec using new in-situ and remote sensing databases, the development of improved snow cover treatment, and a local climate sensitivity analysis in response to various snow-related processes. Team: Environment Canada, Ouranos, Université de Sherbrooke
2. Sila-illusaq The purpose of this project is therefore to study the interactions between snow, vegetation, permafrost and climate at subarctic and Arctic sites in order to quantitatively understand and predict (1) the future thermal regime of permafrost and (2) future GHG emissions from molten permafrost. Team: Takuvik, GAME, LGGE, CEN-UL, INRS-ÉTÉ, UQTR, Université de Sherbrooke, McGill University
3. Suivi de la fonte des calottes glaciaires du Nord par télédétection This project is part of the Natural Resources Canada’s Carto-Nord project to complete topographic coverage of Canada’s North at a scale of 1:50,000, led by the Centre for Topographic Information in Sherbrooke (CIT), in collaboration with the Canada Centre for Remote Sensing. Team: CIT, Université de Sherbrooke, University of Ottawa, Geological Survey of Canada, Parks Canada, CPSP, Canada Centre for Remote Sensing
4. France-Québec collaboration This project is the continuation of a collaboration that has been ongoing for several years between the Université de Sherbrooke and the Laboratoire de Glaciologie et Géophysique de l’Environnement de Grenoble, France. The main goal is to promote and develop innovative methods for measuring snow cover. Team: Université de Sherbrooke, Laboratoire de Glaciologie et Géophysique de l’Environnement (LGGE)-CNRS-Université Joseph Fourier (Grenoble, France), Centre d’Étude de la Neige (Grenoble, France)
5. Monitoring of extreme winter weather events in the Arctic This project focuses on the development of methods for monitoring extreme climate events in the Arctic using in-situ and satellite measurements. In particular, the development of microwave methods is used to monitor rain-on-snow, heat waves and extreme precipitation. Team: Environment Canada, LGGE, CEN-UL, Université de Sherbrooke
6. Monitoring and modelling of winter snowmelt in the Arctic The main goal of the project is to better understand the impact of these winter melt events on the properties of the air-soil-ice interface in order to develop semi-empirical methods for satellite detection of winter melt and to model the snow cover under such conditions. Efforts will focus on two fronts: 1) tundra in Nunavik and 2) the Barnes Ice Cap in Baffin Island, Nunavut. Team: Clark University, UQTR, LGGE, Université de Sherbrooke
7. Improving avalanche risk prediction: measurements and modelling The purpose of this project is to improve the risk modeling from the SNOWPACK model using field measurements. State-of-the-art instruments developed over the past 5 years provide essential information for the realization of the project. Team: Parks Canada, University of Calgary, SLF-Davos, Centre d’avalanche de la Haute Gaspésie, Université de Sherbrooke
8. Assessment of food access conditions of the Caribou Peary in the Canadian Arctic Archipelago by modelling Climate change is causing significant changes in snow conditions, affecting food access conditions for some species, including the Caribou Peary. The project therefore aims to model the state of past, present and future snow cover to determine the spatial and temporal evolution of food access conditions.
