Daily maxima of total water levels from the Global Tide and Surge Reanalysis (GTSR) dataset

GTSR (Global Tide and Surge Reanalysis) is the first global reanalysis of storm surges and extreme sea levels based on hydrodynamic modelling. GTSR covers the entire world's coastline and provides time-series of tides and storm surge from 1979-2014. Tides are simulated with FES2012, while storm surges are simulated by forcing the Global Tide and Surge Model (GTSM) with wind and pressure fields from ERA-Interim. In addition to timeseries, GTSR also provides estimates of extreme sea levels for various return period based on the Gumbel distribution

GTSR（Global Tide and Surge Reanalysis，全球潮汐与风暴潮再分析数据集）是首个基于水动力建模的全球风暴潮与极端海平面再分析数据集。该数据集覆盖全球所有海岸线，提供1979年至2014年的潮汐与风暴潮时间序列数据。潮汐采用FES2012模型进行模拟，风暴潮则通过以ERA-Interim的风场与气压场驱动全球潮汐与风暴潮模型（Global Tide and Surge Model，GTSM）来实现模拟。除时间序列数据外，GTSR还基于耿贝尔分布（Gumbel distribution）提供了不同重现期的极端海平面估算结果。
