This project will facilitate access to historic and future snow cover data across Quebec at a resolution in the order of 10 km. Users and decision-makers from a multitude of sectors will enjoy a broader range of climate information to integrate into their adaptation plans.
Public safety officials, hydrological system managers and hydroclimatology researchers will be able to better assess the impacts of climate change on water resources based on changes in vegetation cover.
The results of this project provide a more complete and precise regional climatic and hydrological portrait in current and future climates to support decision-making on the identification of impacts and adaptation solutions to be planned and implemented for transportation.
By estimating water levels in ungauged areas, virtual stations contribute to the improvement of these essential tools. Based on free, easily accessible images, the approach will provide data on multiple sectors at an almost daily frequency and at little cost.
Once completed, the methodology developed will make it possible to estimate uncertainties in extreme flow values for different return periods for all gauged sites in southern Québec. This knowledge of uncertainty will provide a better understanding of flood events and a better estimation of flood-risk areas.
The project will improve efficiency in the production of climate services and in the traceability of results, as well as improve the consideration of climate science needs by bodies that develop international standards.
This study confirms that the use of scaling laws provides a better characterization of extreme precipitation. Their application will allow for better use of available observational data and thus a better characterization of historical climate, particularly at temporal and spatial resolutions not covered by observational data.
