Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5877. The main objectives are: 1. to fly a novel Ku- and L-band synthetic aperture radar (SAR) system over snow covered tundra land, lakes and sea ice in winter to obtain unique radar observations of these environments; 2. to use collected field measurements acquired by J. Thériault's project (license #5743) at Trail Valle...

Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No. 5676. The objective of this research is to determine: 1) the accuracy of existing physical models of the Interferometric synthetic-aperture radar (InSAR) dry snow signal; 2) if the snow signature can be removed to enable accurate measurement of heave from winter refreezing in the active layer. There are currently three ...

Summary: This licence has been issued for the scientific research application No.5450. The objectives of this integrated monitoring and research project is to provide 1) science based knowledge pertaining to the patterns and rates of climate change, and 2) a quantitative basis for estimating Canada’s contributions to global sea-level rise. Glacier mass balance is defined as the difference between th...

Summary: High resolution Ku-band synthetic aperture radar (SAR) has been proposed to measure Snow Water Equivalent (SWE) from space as part of the proposed Canadian Space Agency Terrestrial Snow Mass Mission (TSMM). An opportunity exists to advance the understanding of the Ku-band radar response to snow properties and develop improved retrieval algorithms using airborne sensors that replicate elements of t...

Summary: The objectives are to work with local residents of Wekweeti to understand how changes in the annual snowpack may impact caribou. The idea is that with increased incursions of warm southern air into the subarctic during winter that snow crusts and ice lenses may be created in the snowpack and as a result increase the energy expenditures of the caribou when foraging for food at the base of the snowp...

Summary: The proposed European Space Agency Earth Explorer 7 CoReH20 satellite mission has the primary objective of retrieving snow water equivalent (SWE) over land at a high spatial resolution (200-500 metres). This would make available high resolution, satellite derived SWE, for monitoring and modeling applications. To-date, airborne measurements to test the CoReH20 satellite mission concept have been ac...

Summary: This research project has two primary scientific goals which include: 1) Relating ground truthed snowpack data to passive microwave data obtained from satellites through the winter months. This will assist in formulating a empirical relationship between the two datasets which is necessary to improve satellite monitoring of snow water equivalent. 2) Determining the relative importance of snowmel...

Licensed Year(s): 2011 2010 2009
Summary: This licence is being issued for the scientific research application no. 982. The objective of this research is to characterize the surface water hydrology at the Thor Lake site and vicinity for at least one hydrologic year. The baseline study is being conducted to aid Avalon Ventures in assessing potential environmental effects of its activities and having adequate environmental information to...

Principal Investigator: Walker, Anne E
Licensed Year(s): 2008
Summary: Environment Canada plans to measure snow depth, snow density and snow water equivalent (water storage in the snowpack), as well as lake ice thickness and structure for comparison with microwave radiometer measurements. Researchers have started to use microwave data from satellites for assessing snow water equivalent (SWE). Field tests to investigate the use of microwave sensors indicate that SW...

Summary: The objective of this project is to understand water and energy fluxes in northern regions, and to develop improved models of these processes. Project studies will look at both the atmospheric and surface water budgets of the Mackenzie Basin, with an emphasis on the effects of climate change on hydrology. The rates and processes controlling accumulation of snow, snowmelt, water flux through sno...
