GIIPSY aims to facilitate the use of current and soon to be launched earth observing satellites to develop broad spectral, medium and high resolution snapshots of the polar regions and use the snapshots as gauges for assessing the impacts of past and future high latitude environmental changes while establishing technical and programmatic infrastructure for sustaining international observations beyond IPY. GIIPSY’s science goals are to: 1)Understand the polar ice sheets to predict their contribution to global sea level rise 2) Understand sea ice sufficiently to predict its response to and influence on global climate change and biological processes 3) Understand glaciers and ice caps in the context of hydrologic and biologic systems and their contributions to global sea level rise 4) Understand the interactions between the changing polar atmosphere and the changes in sea ice, glacial ice, snow extent, and surface melting5) Understand the spatial distribution of permafrost, its interactions with other systems or processes, and predict its response to climate change6) Improve understanding, observing and modeling capabilities of lake and river ice and its influence on energy, water and biochemical cycling, and aquatic ecosystems7) Measure how much water is stored as seasonal snow and its variability
