2 Collaborative Science, Technology, and Applied Research (CSTAR) program Established by the Office of Meteorology* to bring NWS-supported collaborative activities with the academic community into a structured program. Now OCWWS* Program currently under Office of Science & Technology Create a cost-effective transition from basic and applied research to operations and services Grants provided via a competitive grant process to select universities nationally since About $375K every three years

3 Quantitative Precipitation Forecasting (QPF), Hydrology,Tropical/Marine, Modeling and Analysis, Forecast/Warning Processes, Radar Albany/SUNY: Cooperative Research with the NWS on Cool- and Warm-Season Precipitation Forecasting over the Northeastern U.S. Desert Research Institute: Improving WSR-88D QPEs in the Inter-mountain West Florida Institute of Technology: A Real-Time Coupled Wave/Atmospheric Regional Forecast and Analysis System: CWARFS Florida State : Operational system for probabilistic QPF, Ensemble precipitation forecasts, cloud-to-ground lightning climatologies, hydrological modeling for flash flood events Hawaii : Evaluation of Flash Flood Prediction Models for Small Watersheds in Tropical Islands NC State : Improving Understanding and Prediction of Warm Season Precipitation Systems in the Southeastern and Mid-Atlantic Regions, Topographically-forced weather systems in Carolinas and Virginia Oklahoma : A partnership to develop, conduct, and evaluate real-time high-resolution ensemble and deterministic forecasts for convective- scale hazardous weather, Improving Tornado Detection with WSR-88D Using Spectral Analysis Rhode Island : Transitioning coupled hurricane-ocean model to operations Saint Louis: Improved QPF in the Central Region, Improving Prediction of Significant Weather Events in CR Texas A&M: Lightning in the Nowcasting and Warning Process: Cooperative Research Applied to NWS Needs and Priorities Utah : Improved Monitoring, Analysis, and Prediction of High Impact Weather, Numerical Weather Prediction, Local Weather, Mesoscale Observations in Intermountain West Washington : Improvement of Mesoscale Analysis and Prediction, High-resolution numerical weather prediction, grid post-processing, ensemble methodologies, Improving Marine Weather Prediction with Satellite-Derived Products

4 Three Tiers of Projects Major Foci Collaborative – Often trial for projects to upgrade Associate – Supporting Projects Two planning meetings per year (May & November) Major component of NROW Involve many Northeast NWS Offices & CWSUs NOAA Units Leverage the CSTAR grant to other related local NWS office research
