The Reconstructed Sea Level dataset contains sea level anomalies derived from satellite altimetry and tide gauges. The satellite altimetric record provides accurate measurements of sea level with near-global coverage, but it has a relatively short time span, since 1993. Tide gauges have measured sea level over the last 200 years, with some records extending back to 1807, but they only provide regional coverage, not global. Combining satellite altimetry with tide gauges, using a technique known as sea level reconstruction, results in a dataset with the record length of the tide gauges and the n...重建海平面（Reconstructed Sea Level）数据集包含由卫星测高（satellite altimetry）与验潮仪（tide gauges）反演得到的海平面异常数据。卫星测高记录可实现近乎全球覆盖的高精度海平面测量，但其时间跨度相对较短，仅可追溯至1993年。验潮仪的海平面观测记录已有近200年历史，部分记录甚至可回溯至1807年，但其仅能提供区域覆盖，无法实现全球尺度的观测。通过采用名为海平面重建（sea level reconstruction）的技术将卫星测高数据与验潮仪数据相结合，可得到兼具验潮仪记录时长与……的数据集
