An Analysis of Arctic Sea Ice Leads Retrieved from AMSR-E/AMSR2
Remote Sensing, 2022 In this study, we retrieve an Arctic sea ice lead fraction from AMSR2 passive microwave data in winter from 2012 to 2020 based on an algorithm developed for AMSR-E data. The derived AMSR2 sea ice lead fraction is validated against MODIS images.
