NOAA CoastWatch, Sea Surface Height Anomalies and Geostrophic Currents from Altimetry, Global, 2017-present, EXPERIMENTAL

The altimetry data are from RADS (http://rads.tudelft.nl/rads/rads.shtml), the Radar Altimetry Database System, first developed at Delft University of Technology, now also at the NOAA and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The RADS data for each mission is updated with state of the art corrections for tides, atmospheric path delay, etc. Because they are all computed consistently between the various missions, this avoids the possibility of introducing biases and drifts because of the different implementation of the various corrections by different agencies. The goals of RADS are to provide a homogenous dataset of sea level anomalies, wave heights, and wind speeds, along with database selection and analysis tools.

高度计数据源自雷达高度计数据库系统（RADS，http://rads.tudelft.nl/rads/rads.shtml），该系统最初由代尔夫特理工大学开发，现亦由美国国家海洋和大气管理局（NOAA）以及欧洲气象卫星应用组织（EUMETSAT）共同维护。RADS针对每一项任务的数据均进行了最新的潮汐、大气路径延迟等校正。由于这些校正在不同任务间计算一致，因此避免了因不同机构实施校正方法不同而引入偏差和漂移的可能性。RADS的目标是提供一套统一的海洋水位异常、波浪高度和风速数据集，并附带数据库选择和分析工具。
