为了改进海平面气候数据记录，我们比较了来自不同研究机构的TOPEX-Poseidon、Jason-1和Jason-2的19年全球平均海平面（GMSL）时间序列。GMSL时间序列是使用不同的技术和不同的应用校正产生的，因此，时间序列对季节和年际信号表现出独特的特征和敏感性。我们发现，不同的应用校正对时间序列变异性的影响远小于沿航迹与网格海面高度异常计算GMSL技术和选择最小深度标准的影响。
In the interest of improving the sea level climate data record, we compare the 19-year global mean sea level (GMSL) time series derived from TOPEX-Poseidon, Jason-1, and Jason-2 and produced by different research institutions. The GMSL time series are each produced using varying techniques and different applied corrections, and subsequently, the time series exhibit unique characteristics and sensitivity to seasonal and interannual signals. We find that the different applied corrections affect the time series variability much less than the technique for computing the GMSL from along-track versus gridded sea surface height anomalies and the choice of a minimum depth criteria.
