System Performance

The ESDIS Project collects metrics from across the Earth Observation System Data and Information System (EOSDIS). The EOSDIS Distributed Active Archive Centers (DAACs) support different scientific disciplines and provide an individualized set of products and services to their science community and the public. Although discipline oriented, the DAACs engage in common data management functions of ingest, archive and distribution, as well as describing their data and services on web sites.

The navigation links at the upper left take you to annual compilations of system level statistics and to annual reports of the EOSDIS ratings by the American Customer Satisfaction Index (ACSI), as well as other presentations of EOSDIS metrics. An annual summary of the most recent fiscal year statistics appears in the table below.
