Abstract
The Developmental Testbed Center (DTC) has been participating in the Hazardous Weather Testbed's (HWT) SpringForecast Experiment (SFE) in varying capacities for over a decade. In 2024, the DTC continues its collaboration withHWT-SFE by conducting objective verification of several convection allowing models and ensemble (CAM/CAE)systems using an agile framework developed at the DTC over the past several years. This framework is based on the verification capabilities in the Unified Forecast System's (UFS) Short-Range Weather (SRW) App, in turn based on theDTC's MET/METplus verification tool, allowing output from Rapid Refresh Forecast System (RRFS) retros and prototypes as well as other regional CAM-based systems (e.g. NAM nests, HRRRv4, and HREFv3, MPAS-based prototypes) to be quickly verified for a wide range of deterministic and ensemble metrics, both traditional and more novel (e.g. neighborhood verification techniques). In this work, we use the DTC's Agile Framework to perform deterministic verification of several prototypes from the 2024 HWT-SFE, including the operational HRRR as well as multiple MPAS-based configurations from NOAA/NSSL and one from NOAA/GSL. Future work will involve detaching the verification capabilities in the UFS SRW App into a separate repository to allow the SRW as well as other UFS Apps to include it as a component (submodule) with which to perform verification.
