Comprehensive Large Array-data Comprehensive Large Array-data Stewardship SystemStewardship System
NOAA's National Data Centers and their world-wide clientele of customers look to CLASS as the sole NOAA IT infrastructure project in which all current and future large array environmental data sets will reside. CLASS provides permanent, secure storage and safe, efficient access between the Data Centers and the customers.

CLASS OverviewCLASS Overview
CLASS is a web-based data archive and distribution system for NOAA/NESDIS environmental data
Archive … ingest, storage, metadate management, and data quality assurance
Distribution … access, visualization, and data delivery
CLASS is an extension of an 1995 operational system … SAA (Satellite Active Archive)
– Transition to the CLASS architecture began in 2001– “Dual-Site” Operational CLASS began 02 April 2004
CLASS currently supports POES, DMSP, and GOES data sets, plus RadarSat (Synthetic Aperture Radar) and SeaWiFS (Ocean Color Product)
CLASS will support additional campaigns, broader user base, new functionality currently being defined
– CLASS concurrently support ongoing operations and new requirements implementation
