OPERATIONAL STORM SURGE MODELS GENERALLY MAKE USE OF PARAMETRIC/SYNTHETIC STORM MODELS TO GENERATE WIND (AND PRESSURE) FIELDS THAT SERVE AS THE DRIVING FORCE OF THE STORM SURGE CALCULATIONS. IN THIS APPROACH WIND FIELDS ARE CONSTRUCTED FROM A SET OF KEY PHYSICAL PARAMETERS DEFINING THE STORM WHICH INCLUDE FOR EXAMPLE THE STORM CENTER THE MAXIMUM SUSTAINED WIND WIND RADII ETC. UNDER CURRENT MODELING PRACTICES THESE PARAMETERS ARE OBTAINED FROM THE NATIONAL HURRICANE CENTER'S ADVISORY (FOR FORECASTING) AND BEST TRACK (FOR HINDCASTING) DATA WHICH ARE TYPICALLY MADE AVAILABLE OVER SIX HOUR INTERVALS DURING A STORM EVENT. THE UNIQUE SPACE AND TIME COVERAGE OF WIND SPEED MEASUREMENTS PROVIDED BY THE CYCLONE GLOBAL NAVIGATION SATELLITE SYSTEM (CYGNSS) CONSTELLATION OFFERS THE POTENTIAL TO SUPPLEMENT AND IMPROVE UPON THE ESTIMATION OF THESE KEY STORM PARAMETERS DURING THE STORM EVENT THEREBY ULTIMATELY LEADING TO IMPROVED ESTIMATION OF HURRICANE STORM SURGE. THE PROPOSAL FOCUSES ON THE USE OF APPROVED CYGNSS DDM PRODUCTS INCLUDING RECENTLY RELEASED ONES: RAW INTERMEDIATE FREQUENCY AND FULL DDMS. IT MAKES FULL USE OF THE FULL SPATIAL EXTENT OF CYGNSS DDMS AND TEMPORAL SAMPLING TO IMPROVE PARAMETRIC REPRESENTATIONS OF SURFACE WIND SPEEDS IN TCS.
