Class plans providing archive, access, and distribution services for GOES-R data

The Comprehensive Large Array-data Stewardship System (CLASS), a National Oceanic and Atmospheric Administration (NOAA) Information Technology (IT) enterprise solution, supports NOAA's data archive and science data stewardship missions by providing the IT portion of an archive for environmental data. Currently, CLASS is part of a major 10-year growth program to add new data sets and functionality to support a broader user base. The CLASS requirements to support this growth are defined by NOAA's data centers in conjunction with their users and with data producers to ensure that science and other user requirements are clearly defined. These requirements are captured in documents that include requirements specifications, Interface Control Documents, and Submission Agreements that drive the changes needed to handle the future increases in user and data volumes. The paper will present CLASS' approach for other major data campaigns such as NPP, NPOESS, and NEXRAD, historical data, and its plans for going forward with the GOES-R data campaign.
