Comparison of AMSR-E Sea Ice Concentrations with aspect Ship Observations around Antarctica
We compare passive microwave-derived sea ice concentrations with ship-based observations of sea ice concentration (OBS). We focus on different retrieval algorithms that are based on Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) measurements. OBS are collected according to th...
