The Advanced Cooperative Arctic Data and Information Service (ACADIS) was the continuation and expansion of CADIS, or Advanced CADIS. ACADIS was 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).

As of March 28, 2016, the NSF Arctic Data Center serves as the current repository for NSF-funded Arctic data. The ACADIS Gateway is no longer accepting data submissions. All data and metadata in the ACADIS system have been transferred to the NSF Arctic Data Center system.
