| 摘 要： | 利用1995~2003年间的TOPEX/POSEIDON和ERS-2卫星测高数据,尽量采用相同的改正模型对TOPEX和ERS-2卫星测高数据分别进行改正,然后由共线分析法分别推算了全球1°×1°的35 d的海面高异常时间序列,并采用主成分分析法分别对这两个海面高异常时间序列进行了分析。

| Abstract: | The collinear analysis is used to get the time series of sea level anomalies(SLA) by using ERS-2 and TOPEX/POSEIDON altimeter data from July 1995 to November 2003,respectively.To make the comparison between the two time series,the 10 d SLA time series derived from TOPEX/POSEIDON altimeter data is interpolated to 35 d time series.The correction models are harmonized between the two missions.Mean sea surface from 1996 to 1997 is subtracted during the collinear analysis. |
