The Government Resource for Algorithm Verification, Independent Testing, and Evaluation (GRAVITE) is being developed by the Algorithms Division within the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Integrated Program Office (IPO) to facilitate government corporate technical knowledge of the NPOESS science algorithms. GRAVITE consists of a logical technical library, data archive, and an analytical toolset. These three components are used by the Algorithm Division at the IPO and various external partners such as NASA's NPP Science Team, the Operational Algorithm Teams (OATs), and the members of the Internal Government Studies (IGS) Program. The existing infrastructure allows for the development of technical insight, the coordination, communication, and facilitation of Subject Matter Experts (SMEs), and the accumulation and sharing of government technical knowledge. A GRAVITE Lab has been set up in the IPO with dedicated connectivity to the data acquisition, web, and processing servers located at NOAA's Satellite Operations Facility (NSOF) in Suitland, MD. The GRAVITE Lab provides access to data and resources required by the IPO staff to perform Independent Verification and Validation (IV&V) on algorithm and instrument performance, develop Calibration and Validation (Cal/Val) tools and techniques, and execute Government responsibilities for intensive Cal/Val (ICV), and long term monitoring (LTM) activities.
