Dr. Yu Zhang
Current research and/or projects
I joined Canada Centre for Remote Sensing of Natural Resources department in 2000 and have carried out researches on monitoring, understanding, and mapping permafrost and northern ecosystems and their responses to climate change.
Research and/or project statements
Using satellite data and models to monitor and understand permafrost and northern ecosystems and their changes with climate, including:
Monitoring and mapping land surface and permafrost conditions along the Inuvik-Tuktoyaktuk Highway corridor, a project funded by Polar Knowledge Canada science and technology program.
Mapping permafrost distribution and changes with climate at high spatial resolution for infrastructure development and environment assessment.
