An Investigation of Active Microwave Remote Sensing of Summer Sea Ice in the Western Canadian Arctic
Active microwave remote sensing is an important tool for classification of sea ice in polar regions. The aim of this research is to improve the understanding of microwave scattering that occurs during the advanced melt season, with a focus on multiyear ice (MYI). This was done using a combination of...
