Sea ice break-up and freeze-up indicators for users of the Arctic coastal environment

This dataset consists of sea ice indicators for the Arctic based on daily sea ice concentrations derived from satellite passive microwave measurements. The four indicators available are day of break-up start, day of break-up end, day of freeze-up start, and day of freeze-up end. These “day of year” values indicate the ordinal day of the ice-year on which the event occurred. The ice-year is defined as September 1 through August of the following year. Locally defined indicators can serve as key links between pan-Arctic or global indicators such as sea-ice extent or volume and local uses of sea ice, with the potential to inform community-scale adaptation and response.
