Global Systems Laboratory (GSL), part of the Office of Oceanic and Atmospheric Research, seeks to improve Earth-system prediction capabilities across all weather-related hazards including severe convective storms, intense rainfall, winter storms, tropical systems, and phenomena such as wildfire smoke, dust, and pollen. GSL has a rich legacy in developing modeling systems for NOAA operations, including the operational Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR) models, and in contributing to the development of Unified Forecast System (UFS) applications such as the first version of the Rapid Refresh Forecast System (RRFSv1) and the Global Forecast System (GFS). Given the increasing frequency of damaging high-impact weather events in recent years, there is an increasing need for high-resolution modeling systems that can accurately, faithfully, and explicitly resolve precipitating phenomena, fire-weather behavior, aerosol radiative and cloud feedbacks, and urbanization influences to improve forecast skill and inform improved end-user decision-making. Extensive development, testing, and evaluation at GSL and elsewhere over the last two years has indicated that the Model for Prediction Across Scales, or MPAS, can address these predictive needs. My presentation will provide a high-level overview of how the proverbial sauce is made: what is MPAS, how physics processes are represented within MPAS, the vital role of incorporating atmospheric observations to provide an accurate initial atmospheric representation, how extensive computational codebases are maintained, and the importance of rigorous testing and evaluation to guide our scientifically grounded, hypothesis-driven model development activities. I will also present the outcomes of multiple testing and evaluation activities, which demonstrate the substantial promise of MPAS-based weather prediction systems for future NOAA operational weather prediction systems to meet NOAA\u2019s Numerical Weather Prediction Moonshot goal of world-leading skillful, reliable, and useful global, storm-scale, Earth-system model forecasts.
