Abstract

Microsoft PowerPoint - 20140310IGS_Poster_mod.pptx Effects of different footprint areas on the comparability between measurements of sea ice freeboard Sandra Schwegmann1, Stefan Hendricks1, Christian Haas2,3, Andreas Herber1 1 Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany 2 University of Alberta, Edmonton, Canada 3 York University, Toronto, Canada Introduction The significant loss of Arctic sea ice during the last decades shows the sensitivity of the sea ice system to changes in the global climate. To distinguish between natural variability and the impact of global warming, an understanding of processes and feedbacks is necessary, and for that, consistent and comprehensive measurements of the most important sea ice properties are required. Strategies to investigate the sea ice thickness distribution, crucially needed for an investigation of ice mass changes, has only recently been developed. To contribute to the interpretation of the remotely sensed sea ice thickness products, which are mainly based on freeboard determination from altimeter measurements, available airborne sea ice thickness and freeboard data have been collected within the Sea Ice Downstream Services for Arctic and Antarctic Users and Stakeholders (SIDARUS) EU-Project, and have been analyzed with respect to their usability for validation of the large scale satellite products. One major challenge in comparing satellite and airborne measurements is the different footprint area of these methods. Therefore, statistical parameters like the variability of freeboard within the common footprint areas have been analysed from measurements made during the PAMARCMIP 2011 campaign in order to determine the differences between point measurements and areal averages.
