| Abstract: | A detailed analysis and comparison of 7 represented altimeter model functions are presented, which have been published in the open literature, based on the collocted and coincident data between TOPEX/Poseidon altimeter and buoy observations. It is shown that the analytical algorithm considered the effect of wave state is superior to this empirical one as a whole. The issue of deriving wave period from altimeter is also discussed, and the results scatter largely. The possible way of improving wave-period algorithm is suggested. |
