Open access data to inform researchers, policymakers, and others
NSIDC’s data management programs focus on preserving and providing access to cryospheric data and related geophysical data. Our three programs include the NASA NSIDC Distributed Active Archive Center (DAAC), the National Oceanic and Atmospheric Administration at NSIDC (NOAA@NSIDC), and the Exchange for Local Observations and Knowledge of the Arctic (ELOKA). Each program brings a unique expertise to NSIDC, allowing us to manage and distribute a vast and varied collection of data and data resources.
