GOES-R and JPSS Proving Ground Demonstration at the Hazardous Weather Testbed 2025 Spring Experiment: Final Evaluation

This report summarizes the activities and results from the Geostationary Operational Environmental Satellite R-Series (GOES-R) and Joint Polar Satellite System (JPSS) Proving Ground demonstration at the 2025 Spring Experiment, which took place virtually at the National Oceanic and Atmospheric Administration (NOAA) Hazardous Weather Testbed (HWT) in Norman, Oklahoma from 5 May to 6 June 2025. This year featured 17 National Weather Service (NWS) forecasters participating in the EWP experiment, along with 18 product developers and visiting scientists. All NWS forecasters were from Weather Forecast Offices (WFOs) in four NWS regions. This group evaluated three experimental GOES-R products in the real-time simulated short-term forecasting, decision support service (DSS), and warning environment of the Experimental Warning Program (EWP). Additionally, they used cloud-based instances of the second-generation Advanced Weather Interactive Processing System (AWIPS-II) and web-based interfaces to interact with the experimental products. Organizations represented by the visiting scientists included four NOAA Cooperative Institutes, three NOAA line offices, and one external organization.
