Notice: Due to funding limitations, this data set was recently changed to a “Basic” Level of Service.
Description
Learn more about what this means for users and how you can share your story here: Level of Service Update for Data Products . The Sea Ice Index provides a quick look at Arctic- and Antarctic-wide changes in sea ice.
It is a source for consistent, up-to-date sea ice extent and concentration images, in PNG format, and data values, in GeoTIFF and ASCII text files, from November 1978 to the present. Sea Ice Index images also depict trends and anomalies in ice cover calculated using a 30-year reference period of 1981 through 2010. The images and data are produced in a consistent way that makes the Index time-series appropriate for use when looking at long-term trends in sea ice cover.

Both monthly and daily products are available. However, monthly products are better to use for long-term trend analysis because errors in the daily product tend to be averaged out in the monthly product and because day-to-day variations are often the result of short-term weather.
