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.
