Abstract:
The use of groundbased GPS network (e.g., Suominet, [Ware et al., 2000]) and spaceborne GPS-to-Low-Earth-Orbiter (LEO) GPS limb-sounding techniques for retrieving atmospheric profiles have been demonstrated [e.g., Rocken et al., 1997]. GPS has also been used as a water level measurement [e.g., Parke et al., 1997] and for radar altimeter calibration. In this paper, we will discuss the use of the proposed Ohio State University continuous GPS stations (located in Columbus, Lake Erie, and Gulf of Mexico offshore oil platform) and buoy equipped GPS receivers as a measurement system of atmospheric water vapor, sea level, and for absolute calibrations of spaceborne radar altimeters. Furthermore, water vapor measurements sampled in space and time will be discussed using the groundbased stations and the current and future spaceborne measurements for the potential of near-real time retrieval of atmospheric profiles to improve regional weather forecasting.
