摘 要: 联合验潮站和卫星测高数据进行重构是目前获取长时间全球平均海平面变化序列的主要方法。对目前这一方法的研究进展进行较为系统的总结,指出重构中存在的主要问题,并选取两个典型的重构结果,针对其确定的海平面变化速率,利用多源测高数据确定的1993年至今海平面变化序列,以及经过垂直运动改正后的验潮站数据确定的海平面变化进行比较和验证。结果表明,在重构中获取的海平面变化速率还存在一定的不确定性,对所选取参与重构的验潮站数据有较强的依赖。

Abstract: It is the main method to obtain the long time series of global mean sea level change by combing the tide gauge and satellite altimetry data. This paper summarizes the current research progress of the reconstruction method, points out the main problems existing in the reconstruction. And two typical reconstruction results are selected to be compared and analyzed by pure satellite altimetry and tide gauge data. Aiming at the conforming rate of sea level change, the time series of sea level change is determined by using multi-altimetry data since 1993, and the result of tide gauges, are compared and verified after corrected for the vertical motions. The results show that there are still some uncertainties in the obtained rates of sea level change by reconstruction, and the results have a strong dependence on the selection of tide gauge data participated in the reconstruction.
Key words: geodetic technology; sea level change; reconstruction; satellite altimetry; tide gauge
