Welcome to the Advanced Cooperative Arctic Data and Information Service (ACADIS)

The Advanced Cooperative Arctic Data and Information Service (ACADIS) is a joint effort by the National Snow and Ice Data Center (NSIDC), the University Corporation for Atmospheric Research (UCAR), UNIDATA, and the National Center for Atmospheric Research (NCAR) to provide data archival, preservation and access for all projects funded by NSF's Arctic Science Program (ARC). ACADIS builds on the CADIS project that supported the Arctic Observing Network (AON). This portal will continue to be a gateway for AON data and is being expanded to include all NSF ARC data.

ACADIS provides a template to assist investigators in developing the Data Management Plan required for all NSF proposals.

To contribute your data:

If you are an OPP-ARC Investigator, please contribute your data and metadata.
If you are another Arctic investigator who would like to contribute data not funded by ARC, please contact support@aoncadis.org

Search for Data

Search for data using variable, principal investigator, discipline, temporal/spatial coverage, and other parameters.

View Projects Geographically

Each of the options below represent a different way to view the project locations (or the location of a component of each project). Click on an icon to view that option in a new window.

MapServer shows... Selected NSF-funded Arctic projects with the option of displaying alongside other field projects supported by NCAR.

The ACADIS Web Map Viewer shows... The locations of Arctic Observing Network projects with the option of showing other NSF funded work through ARMAP. We suggest you START HERE unless you prefer a full GIS or Google Earth interface.

Google Earth shows... NSF-funded Arctic projects hosted on or associated with ACADIS, with the option of layering KML-format data files such as sea ice extent.
