ATLAS/ICESat-2 L3B Monthly Gridded Dynamic Ocean Topography, Version 3

This data set contains monthly gridded dynamic ocean topography (DOT), derived from along-track ATLAS/ICESat-2 L3A Ocean Surface Height product (ATL12). Monthly gridded sea surface height (SSH) can be calculated by adding the mean DOT and the weighted average geoid height also provided in this data set. Both single beam and all-beam gridded averages are available in this data set. Single beam averages are useful to identify biases among the beams and the all-beam averages are advised to use for physical oceanography.

本数据集包含源自沿轨ATLAS/ICESat-2 L3A海洋表面高度产品（ATL12）的网格化逐月海洋动力地形（DOT）。通过将平均海洋动力地形与本数据集同步提供的加权平均大地水准面高度相加，即可计算得到网格化逐月海面高度（SSH）。本数据集同时提供单波束与全波束的网格化平均值，其中单波束平均值可用于识别各波束间的偏差，而物理海洋学研究推荐采用全波束平均值。
