Storm Surge Measurement Potential of the Wide Swath Radar Altimeter Ivan PopStefanija 1 , Edward J. Walsh 2 (popstefanija@prosensing.com) 1 ProSensing; 2 NOAA/ESRL/PSD The Wide Swath Radar Altimeter (WSRA) has the potential to provide operational, targeted measurements of storm surge for land-falling hurricanes. The concept of airborne measurement of storm surge consists of subtracting the absolute altitude of the aircraft determined using the Global Positioning System (GPS) from the WSRA-measured distance to the sea surface. The result of that simple calculation is the absolute elevation of the water for the particular point in time and space. Wright, et al. (2009) demonstrated the technique in a research mode using the NASA Scanning Radar Altimeter (SRA) which has since been decommissioned. The absolute range calibration of the WSRA can be determined and maintained during the flights using tide gauges within Tampa Bay when returning from each operation, as well as flying by tide gauges in the vicinity of the landfall. The poster examines the range accuracy of the WSRA and demonstrates the absolute calibration technique using a data segment over Tampa Bay when N42RF was returning from a flight into Hurricane Ike on September, 11 2008. Historical SRA data are used to demonstrate the potential benefits of targeted storm surge measurements. Poster Session – Page 6
Direct Interpretation of COSMIC Refractivity Data in the Tropical Cyclone Environment Christopher M. Hill, Patrick J. Fitzpatrick, and Yee Lau (hillcm@gri.msstate.edu) Geosystems Research Institute, Mississippi State University, Stennis Space Center, MS This study continues to explore the utility of the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) in measuring moisture in the vicinity of tropical cyclones. From a formula relating GPS signal refractivity to temperature, pressure, and vapor pressure (Smith and Weintraub 1953, Kursinski et al. 1995), especially high (low) values of refractivity at a known pressure level correspond to high (low) vapor pressure in a relatively high temperature environment. The implication is that a relative measure of moisture can be attained with only refractivity at a known pressure level, and without specific knowledge of temperature, in a tropical environment. The relation of refractivity to tropospheric thermodynamics further yields a critical value of refractivity below which water vapor saturation – and therefore clouds – cannot exist at a known pressure level. The above findings are applied in the evaluation of a June-September climatology of COSMIC refractivity over the tropical and subtropical eastern Atlantic Ocean, as well as in the evaluation of individual COSMIC refractivity profiles with varying proximity to select Atlantic tropical cyclones. Nomograms relating refractivity to pressure and temperature have been constructed to assist in the determination of moisture content for given values of refractivity and pressure.
