This dataset contains the Global Mean Sea Level (GMSL) trend generated from the Integrated Multi-Mission Ocean Altimeter Data for Climate Research Version 5.2. The GMSL trend is a 1-dimensional time series of globally averaged Sea Surface Height Anomalies (SSHA) from TOPEX/Poseidon, Jason-1, OSTM/Jason-2, Jason-3, and Sentinel-6A that covers September 1992 to present with a lag of up to 4 months. The data are reported as variations relative to a 20-year TOPEX/Jason collinear mean. Bias adjustments and cross-calibrations were applied to ensure SSHA data are consistent across the missions; Glaci...

本数据集包含源自气候研究多任务集成海洋高度计数据集（版本5.2）的全球平均海平面（GMSL）趋势数据。该全球平均海平面趋势为基于TOPEX/Poseidon、Jason-1、OSTM/Jason-2、Jason-3及Sentinel-6A卫星任务获取的全球平均海面高度异常（SSHA）构建的一维时间序列，时间覆盖区间为1992年9月至今，数据存在最长4个月的滞后。所有数据均以相对于20年TOPEX/Jason共线参考均值的变化量形式报告。为确保不同卫星任务间的海面高度异常数据保持一致性，研究人员已对数据施加偏差校正与交叉定标处理；冰川……
