Across the globe, snow and ice play a vital role in regulating Earth’s climate and providing freshwater resources to people, plants, and animals.

As Earth’s frozen regions change rapidly, NSIDC is committed to growing its research and open access data to better understand these changes. Read about NSIDC research and its contribution to science and policy making. Check out spotlights on how to use NSIDC data, tools, and resources. Learn about how we steward data and collaborate with scientists and organizations across the world to understand how the frozen parts of Earth affect the rest of the planet and impact society.

As NASA moves their data, including data collections managed and housed at their 12 distributed active archive centers (DAACs), over to the Earthdata Cloud, the organization will lean on Openscapes. To support NASA DAAC researchers during the data migration to the cloud, Openscapes developed the Openscapes Framework, a scalable leadership training and community-building framework which includes three components: engaging DAAC mentors, empowering science research teams, and amplifying open science leaders.
