To prepare for managing the transition to an Arctic that is nearly ice free in the summer, it is critical to have accurate projections of Arctic environmental changes over the next several decades. Forecasts of regional sea-ice conditions on seasonal timescales can help different stakeholders prepare for and adapt to the impacts of climate change and minimize environmental risks associated with development.

They provide information at scales, locations, and time periods that are extraordinarily important in advancing our knowledge of critical processes during this era of rapid loss and transformation of Arctic sea ice. There are no other data available that show the melting and freezing processes that we were able to observe in these images; their release will have a major impact on understanding effects of climate change on sea ice and ice habitat.

Ice Topography and Albedo: There are virtually no sustained, systematic observations of the evolution of the spatial variability in ice albedo because neither radar nor passive microwave images have sufficient resolution. The LIDPs will provide an unprecedented view of how the surface topography affects the initial formation and subsequent evolution of melt ponds and their effect on the albedo and hence the shortwave radiative energy balance.

Beaufort Sea: The Beaufort Sea, with imagery dating to 1999, exhibits the broadest range of different ice types and ice ages, greatly increasing the value of Arctic sea-ice LIDPs in improving our ability to monitor and forecast the movement and evolution of different ice age and thickness classes. Forecasts of regional sea-ice conditions on seasonal timescales can help different stakeholders prepare for and adapt to the impacts of climate change and minimize environmental risks associated with industrial activity.
