摘要
A new method to derive the seasonal elevation signal from a continuous time series of altimeter crossover data is presented. The method utilizes the complete set of intrasatellite crossover data to provide fine temporal resolution and to significantly reduce random measurement errors. This is an improvement over the standard time-series method that only uses those data referenced to a single lime period at the beginning of the satellite mission.
