HORIZON Framework for Distributed Data Management and Product Generation Workflow

The NASA Earth Observing System Data and Information System (EOSDIS) is a data-centric system designed for the processing and archiving from NASA’s Earth Observation missions and their distribution, as well as provision of specialized services to users. The major components of EOSDIS are 12 Distributed Active Archive Centers (DAACs), 14 Science Investigator-led Processing Systems (SIPSs), and the EOS Clearing House (ECHO). The DAACs play an import role within EOSDIS. They are divided by discipline with User Working Groups (UWGs) tailored to mission and objectives of the DAAC.
