Third, they are produced in the context of sustained services offering committed extension, documentation, traceability, and user support. Second, they are based on dynamic tie points, which capture the time evolution of surface characteristics of the ice cover and accommodate potential calibration differences between satellite missions. These three records are derived from passive microwave satellite data and offer three distinct advantages compared to existing records: first, all three records provide quantitative information on uncertainty and possibly applied filtering at every grid point and every time step. We introduce the OSI-450, the SICCI-25km and the SICCI-50km climate data records of gridded global sea-ice concentration.
The workshops were supported by the Svalbard Strategic Grant SSG, (The Research Council of Norway), with the aim of fostering international cooperation, open sharing of data, coordination of logistics, the use of new technologies, and to reduce the environmental impact of fieldwork. Given the challenges of maritime users often working on multiple temporal and spatial scales at any given time, it is essential that the information providers (researchers, forecasters) understand the difference between the use of products that are appropriate for projections of sea ice extent for future investment and policy, and those that are more suitable for planning and supporting operations (Wagner et al, 2020). The aim was to better understand user needs in Arctic operations and planning, and more specifically to explore whether the development of sea ice forecasts can be useful for future maritime operations and planning, particularly along the ice edge and marginal ice zone (MIZ). Two virtual conferences brought together participants from forecasting, operations, climate and sea ice forecasting, economics, and planning.
