高度计风速反演算法比较及波浪周期反演初探
On altimeter wind speed model functions and retrieval of wave period
-
摘要: 利用浮标实测数据和TOPEX/Poseidon高度计资料的时空配准数据,对迄今为止已提出的有代表性的7种卫星高度计海面风速反演模式函数进行了分析比较,指出考虑波浪状态影响的解析算法在均方根误差和对称性方面的优越性,讨论了目前在波浪周期反演方面存在的问题以及可能的解决途径.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.
