Datasets managed by the NSF Arctic Data Center and archived at the NOAA National Centers for Environmental Information

Description

The National Science Foundation (NSF) Arctic Data Center (ADC) preserves and provides access to multi-disciplinary NSF-funded global cryosphere-land-ocean-atmosphere data (including in situ and remote sensing, video, sound, and other data). This collection includes all such data which has been provided to and has been archived by the NOAA National Centers for Environmental Information (NCEI). The data span from 1800 to present and include many measured variables and calculated parameters.
