| الوصف: | The Report describes the PhD dissertation research completed by Kai-chien Cheng in September, 2005, supervised by Professor C.K. Shum and other PhD Committee Members including Profs. Michael Bevis, Stéphane Calmant, and Burkhard Schaffrin. ; This research is supported by grants from National Aeronautics and Space Administration's Ocean, Ice and Climate Program (NNG04GA53G and NNG04GN19G), Earth Science Enterprise Program (NGA5-12585) and Earth Observing System Interdisciplinary Science Program (NAG5-9335), National Science Foundation's Information and Intelligent Systems Digital Government Program (IIS-0091494), and the Ohio Sea Grant (No. R/CE-5) via funding from the National Oceanic and Atmospheric Administration. ; Accurate knowledge about sea level and its change is essential to humanity because a large proportion of the Earth's population lives in coastal regions. This study discusses the existing techniques for sea level measurements, including the use of different types of gauges (e.g., water level gauge or tide gauge, and bottom pressure gauge), as well as GPS and satellite altimetry. The GPS water level measurements from a buoy or a vessel are presented and utilized in this study along with other techniques to collect ellipsoidal, geocentric sea surface height measurements for various studies that help improve our knowledge about sea level and its change. An operational technique of using GPS water level measurement is proposed in this study. The limitation and an upper bound accuracy of the kinematic (epoch-by-epoch) positioning in terms of baseline length are discussed. A set of GPS data in Lake Erie, including buoy data as well as a local GPS network on land, are used to provide the numerical results. Three main applications of using the GPS water level measurements are presented in this study. They are integration of various data sources in the coastal, satellite radar calibration, and GPS hydrology. The objective of these applications is to demonstrate the potential of the GPS technique in ... |
