DTU23 Global Ocean Tide model (DTU23_OceanTide)

The newest version of the DTU global 1/6 degree ocean tide models derived from satellite altimetry given on similar resolution to the FES2014 ocean tide model.The spatial resolution is 1/16 degree corresponding to 6 km at the Equator. The model contains 10 constituents and is provided with interpolation software to deduce 30 additional minor tidal constituents.The model is mainly and update to the previous global ocean tide models (DTU16) in the polar regions.

本数据集为基于卫星测高数据构建的最新版DTU全球1/6度海洋潮汐模型，其空间分辨率与FES2014海洋潮汐模型相当。该模型的空间分辨率为1/16度，在赤道区域对应约6公里的尺度。模型包含10个主要潮汐分潮，并配套插值软件，可推导得到额外30个次要潮汐分潮。本模型主要针对极地区域，对前代全球海洋潮汐模型（DTU16）进行了升级优化。
