This page provides access to Arctic and Antarctic data, services, and information across NOAA line offices and partners. NOAA has several substantial Arctic observing systems including operational weather satellites and subject matter expertise that support the sustainability and well being of communities, and contribute to scientific environmental stewardship. The Arctic and Antarctic Polar regions are vulnerable to rapid extreme weather events and climate variability impacts and feedback processes. These regions also have implications for national safety and security, international cooperation and trade, and strategic importance to the U.S.
