Overview

NSIDC offers a wide variety of sea ice products derived from passive microwave sensors, visible and infrared sensors, and other sources. Sea ice is a critical component of our planet because it influences our global climate even though sea ice occurs primarily in the polar regions. These Web pages are designed to help you make an educated decision about the most appropriate sea ice product for your research.

The pages of this Web site can be accessed with the navigation to the left. The Data Sets Web page describes the current sea ice data product holdings at NSIDC. The Tools Web page provides a list of tools for accessing, displaying, and geolocating the sea ice data. The Other Data Sources Web page provides links to other sources of sea ice data and information, and the FAQs Web page lists some of the most frequently asked questions about NSIDC sea ice data. For more information about sea ice and how it affects our climate, see the All About Sea Ice Web page.
