Development of a near-real-time GOES-based satellite verification and forecaster guidance system for the HRRR model
For this presentation, we will describe the current and future capabilities of the analysis system. Synthetic GOES infrared brightness temperatures are generated during each HRRR model forecast cycle using the Community Radiative Transfer Model (CRTM) and are then compared to real GOES observations using various statistical methods in order to assess the accuracy of the cloud and moisture fields at each model forecast time. Because forecast skill often varies with space and time, these statistics are computed for pre-defined regions across the contiguous U.S. Forecasters can easily access the satellite-based verification results via an interactive webpage and sort the model forecast accuracy based on a given statistical measure. GOES, and eventually GOES-R, observations are critical for this verification system because they provide unique information about the spatial distribution of water vapor and clouds associated with various hazardous weather phenomena such as severe thunderstorms, winter storms, and turbulence.
