Abstract

Abstract

The difference-ratio relations are introduced to separate tidal constituents that are aliased due to the sample interval of the TOPEX/POSEIDON altimeter.It is found that some tidal constituents such as K₁ and SSA,though aliased at along track points,are not aliased at crossover points because there is one time more data at crossover points than that at along track points.So the harmonic analysis method can be employed directly on time series at the crossover points.Then the difference-ratio relations from the crossover points are introduced to analyze the time series at along track points.The TOPEX/POSEIDON data in the Northwest Pacific are analyzed with this method. The results from this method agree well with tidal constants from tidal gauges.
