Interagency Implementation and Advanced Concepts (IMPACT) Team members Kaylin Bugbee, Jeanné le Roux, Aaron Kaulfus, Camille Woods and Rahul Ramachandran (ST11) in collaboration with the Earth Science Data and Information System (ESDIS) team members Christopher Lynnes and Valerie Dixon, were co-authors on a journal article entitled “Improving Discovery and Use of NASA’s Earth Observation Data Through Metadata Quality Assessments” published in Data Science Journal on 4/28/21. The article describes the IMPACT Analysis and Review of Content Metadata Repository (ARC) team’s framework to assess the quality of NASA’s Earth observation metadata with the overarching goal of improving the discoverability, accessibility and usability of the data it describes. The ARC team, in close collaboration with NASA’s twelve Distributed Active Archive Centers (DAACs) and the ESDIS Project, have made significant improvements in metadata quality to date, with results continuing to improve as more metadata is updated.
