Product Quality determination across all science products on GOES-R series satellites is overseen by a cross-collaborative group as part of the calibration/validation (cal/val) coordination team (CVCT). Instrument cal/val as well as Level-1b (L1b) and Level 2+ (L2+) product validations are essential to GOES-R series mission success. Pre-launch verification determines that an instrument system, subsystem or component is functioning within requirements. Calibration and characterization continue after launch as a means to maintain quality of the GOES-R L1b and L2+ data products. Validation is the process of determining that the deliverable item satisfies its intended use in its intended environment. Most all GOES-R instrument, L1b, and L2+ product validation is fully realized after launch with actual earth observations.
There are many entities involved in calibration and product validation. Overall, the Ground Segment Project (GSP) is responsible for executing L1b and L2+ product science validation. Within the GSP, the Product Readiness and Operations (PRO) team coordinates the CVCT. The CVCT is comprised of groups responsible for validation testing post-launch of the science products, including:
Milestones of science product maturity are marked by holding a Peer/Stakeholder Product Validation Review (PS-PVR). This review appraises the status of product quality with respect to Program definitions. The panel chair is the GOES-R Program Scientist. The panel chair declares products have achieved a maturity level and provides guidance on the path forward to the next maturity level through the chair disposition form. Other members of the panel include GOES-R Program, Office of Satellite Products and Operations (OSPO), Geostationary Satellite Operational Requirements Working Group (GORWG), Office of Satellite Ground Services (OSGS), the Calibration Working Group (CWG), and the Algorithm Working Group (AWG).
The GOES-R Program definitions of the three levels of product maturity are:
