Site introduction

The National Snow and Ice Data Center (NSIDC) is a research and data organization at the University of Colorado Boulder, part of CIRES. It serves as a authoritative source for information on snow, ice, glaciers, ice sheets, sea ice, and frozen ground, combining scientific research with public education.

The site’s Ask a Scientist section answers common questions about the cryosphere in plain language, such as this explanation of the Karakoram Anomaly, where glaciers have shown modest gains while most mountain glaciers lose ice. NSIDC also offers data archives, analysis pages like Sea Ice Today and Snow Today, a cryosphere glossary, and multimedia resources.

NSIDC is suited to researchers, students, educators, journalists, and anyone interested in climate and polar science who needs reliable, citable information. Data users can access NASA Earthdata resources and distributed active archive services.

For best use, start with the Learn section for background concepts, then explore data tools and analysis pages for current conditions. The Ask a Scientist pages are ideal for quick, expert-vetted answers to specific questions. Overall, NSIDC is a dependable reference for cryosphere science and data.
