A key objective of the CliC programme is to improve the representation, in global climate models, of interactions between sea ice, the oceans and the atmosphere (CliC, 2000). Due to the high albedo of sea ice, low thermal conductivity and its affect on the thermohaline budget, sea ice profoundly affects the exchanges of heat, water and momentum between the ocean and atmosphere, and plays an important role in oceanic convection and deep-water formation. The GlobICE Project is a part of ESA's Data User Element (DUE) of the Earth Observation Envelope Programme. The main purpose of GlobICE is to derive information on sea ice that will improve understanding of the role of the Arctic in global climate in support of CliC and World Climate Research Programme objectives. The input to the project is earth observation data mainly from ESA’s ENVISAT ASAR archives and supplemented by radar altimeter data. The GlobICE information system provides validated sea-ice motion, deformation and flux products derived from the available radar data. This paper will describe the family of GlobIce data products, present their potential applications and summarize the feedback from climate modellers and other key user groups who have assessed the products.
