Absolute sea level changes along the coast of China from tide gauges, GNSS and satellite altimetry

The datasets are used for the study of absolute sea level changes along the coast of China from tide gauges, GNSS and satellite altimetry. There are five folders containing the data of GNSS, tide gauge, land freshwater runoff and the results extraction from AVISO grid products. A data description is included in the datasets.本数据集用于依托验潮仪、全球导航卫星系统（GNSS）与卫星测高数据，开展中国沿海绝对海平面变化相关研究。数据集包含五个子文件夹，分别存储全球导航卫星系统、验潮仪、陆地淡水径流以及从AVISO网格产品中提取的结果相关数据。数据集内附带数据说明文档。
