These metrics reflect metadata submissions and usage of the NGEE Arctic Data Search Tool (Figs. 9–11). Metadata records reflect a combination of data, information, and documentation that form a collection. While Although all metadata records are available to the public, researchers may request that some data collections be accessible only to the NGEE Arctic team. Currently, we have 174 metadata records are available, with 112 collections released to the public and 62 in the internal-only or planned stages. The search tool tracks the number of unique users and the number of downloads of any part of a collection.
