ECCC Global Coastal Total Sea Level Hindcast, Version 1 (ECCC_GTSLv1)

ECCC-GTSLv1 was produced based on ECCC's Global Deterministic storm Surge Prediction System (GDSPS). The dataset dynamically accounts for contributions from storm surges, tides, baroclinicity, and their nonlinear interactions. Special efforts have been made to include or improve these components through nudging of deep water tidal transports, nudging of 3D temperature and salinity, and by calibrating the wind drag coefficient. The dataset includes both the shoreline grid data produced by the control run (YYYY_shoreline.nc.gz and shoreline_lonlat.nc.gz) and tide-gauge data (tide_gauge.tar.gz) An recent updated version (ECCC-GTSLv2, https://doi.org/10.5281/zenodo.20380403) addresses the gap arising from underrepresented small to medium sized tropical cyclones.本数据集为时长65年的高分辨率（1/12度）全球沿海总海平面数据集（GTSL65），由加拿大环境与气候变化部（ECCC）的全球确定性风暴潮预报系统（GDSPS）构建而成。GTSL65动态涵盖了风暴潮、潮汐、斜压性及其非线性相互作用的贡献项。为纳入并完善上述各分量，本数据集通过对深水潮汐输运施加逼近校正、对三维温盐场进行逼近校正，以及校准风拖曳系数等手段完成了专项优化。 本数据集包含控制试验生成的岸线格点数据（YYYY_shoreline.nc.gz与shoreline_lonlat.nc.gz），以及Wang与Bernier（2025）研究中使用的验潮站数据（tide_gauge.tar.gz）。相关DOI链接：https://doi.org/10.1016/j.wace.2025.100805 注：为消除模型自旋启动阶段的影响，1958年的前40天数据已被剔除。 后续版本将弥补未解析小型热带气旋所带来的数据缺口。
