The Earth Observing System Data and Information System (EOSDIS) is designed to archive unprecedented amounts of Earth observing data from a wide range of instruments collecting information over decades. Its diverse user community can search, retrieve, and analyze any of these observations, also over a period of decades. EOS data products need descriptive information, or metadata, to enable users and data providers to locate and use the information. Over several years, numerous teams of scientists, computer scientists, and information engineers have collaborated to develop the data model, with its metadata attributes and how they are organized, to meet these needs.
This page provides an introduction to metadata in EOSDIS. It focuses on the information data providers and instrument teams need in order to interface with EOSDIS.
