National Snow and Ice Data Center

Service Provider Description
The National Snow and Ice Data Center (NSIDC) supports research into our world's frozen realms: the snow, ice, glaciers, frozen ground, and climate interactions that make up Earth's cryosphere.

NSIDC manages and distributes scientific data, creates tools for data access, supports data users, performs scientific research, and educates the public about the cryosphere.

NSIDC distributes more than 500 cryospheric data sets for researchers, from both satellite and ground observations.

The National Snow and Ice Data Center (NSIDC) is part of the University of Colorado Boulder Cooperative Institute for Research in Environmental Sciences (CIRES), and is affiliated with the National Oceanic and Atmospheric Administration (NOAA) National Geophysical Data Center (NGDC) through a cooperative agreement. Areas covered include freshwater ice, polar ice sheets, glacier fluctuations, sea ice, glacier mass balance, seasonal snow cover, ground ice (permafrost) and extraterrestrial ice.
NSIDC manages and disseminates scientific data for NASA, the National Science Foundation (NSF), NOAA, and other Federal sponsors. Major data management programs include:

1) NSIDC Distributed Active Archive Center (NSIDC DAAC)
NSIDC participates as one of the NASA-funded Distributed Active Archive Centers (DAACs) in the Earth Observing System Data and Information System Project (EOSDIS). The Earth Observing System (EOS) is a long-term interdisciplinary and multidisciplinary research effort to study global-scale processes that shape and influence the Earth as a system. EOSDIS manages the data resulting from NASA's research satellites and field measurement programs, and other data essential for the interpretation of these measurements. It also facilitates access to data held in the archives of other government agencies, organizations, and countries. Major data offerings include AMSR-E, IceSAT/GLAS, MODIS, Operation IceBridge, and passive microwave data from Defense Meteorological Satellite Program (DMSP) satellites.

2) Advanced - Cooperative Arctic Data and Information Service (A-CADIS)
A-CADIS is the continuation and expansion of CADIS, or Advanced CADIS. The Advanced Cooperative Arctic Data and Information Service (A-CADIS) is a joint effort between the National Snow and Ice Data Center (NSIDC), the National Center for Atmospheric Research (NCAR), and Unidata to manage the diverse data needs of the Arctic research community supported by the National Science Foundation (NSF) Office of Polar Programs (OPP). This includes, but is not limited to, projects funded under the Arctic Observing Network (AON), Arctic System Sciences, Arctic Natural Sciences, and the Arctic Social Sciences Program. ACADIS represents an evolution of the CADIS that focused on the AON community. The National Science Foundation's Office of Polar Programs Arctic Section (ARC) supports A-CADIS to provide data management support for investigators funded under NSF/OPP/ARC.

3) Antarctic Glaciological Data Center (AGDC)
The AGDC at the National Snow and Ice Data Center (NSIDC) archives and distributes Antarctic glaciological and cryospheric system data collected by the U.S. Antarctic Program. The AGDC Data Catalog contains data sets collected by individual investigators and products assembled from many different PI data sets, published literature, and other sources. The catalog provides useful compilations of important geophysical parameters, such as accumulation rate or ice velocity.

4) Exchange for Local Observations and Knowledge of the Arctic
ELOKA facilitates the collection, preservation, exchange, and use of local observations and knowledge of the Arctic. ELOKA provides data management and user support, and fosters collaboration between resident Arctic experts and visiting researchers. By working together, Arctic residents and researchers can make significant contributions to understanding the Arctic and recent changes.5) NSF Antarctic Glaciological Data Center

The National Oceanic and Atmospheric Administration (NOAA) team at NSIDC manages, archives, and publishes data sets with an emphasis on in situ data, data sets from operational communities such as the U.S. Navy, and digitizing old and sometimes forgotten but valuable analog data. We also help develop educational pages, contribute to larger center-wide projects, and support the Roger G. Barry Resource Office for Cryospheric Studies (ROCS) at NSIDC.
