Challenges in determining snow water equivalent over Canada using microwave radiometry

The paper describes Canadian accomplishments in deriving snow water equivalent (SWE) using satellite passive microwave data for varying climatic and landscape conditions in western and eastern Canada and the Canadian Arctic. It summarizes related algorithm development and validation and identifies challenges in producing reliable SWE products for climatological and hydrological use, monitoring the state of the cryosphere, and enhancing our understanding of cryospheric processes and variability
