资源简介：

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. cdm_data_type=Grid Conventions=CF-1.6, COARDS, ACDD-1.3 cw_processing_algorithm=RADS 4.2.5 cw_product_status=Experimental cw_satellite=Jason-2 CryoSat-2 SARAL Jason-3 Sentinel-3A Easternmost_Easting=179.875 geospatial_lat_max=89.875 geospatial_lat_min=-89.875 geospatial_lat_resolution=0.25 geospatial_lat_units=degrees_north geospatial_lon_max=179.875 geospatial_lon_min=-179.875 geospatial_lon_resolution=0.25 geospatial_lon_units=degrees_east history=Data from Radar Altimetry Database System (RADS) http://rads.tudelft.nl/rads/rads.shtml Every day, erd.data@noaa.gov at NOAA NMFS SWFSC ERD downloads new data from ftp://ftp.star.nesdis.noaa.gov:/pub/socd/lsa/rads/sla/daily/nrt id=nesdisSSH1day infoUrl=https://coastwatch.noaa.gov/cw_html/SSH_SeaLevelAnomaly.html institution=NOAA/NESDIS Center for Satellite Applications and Research keywords_vocabulary=GCMD Science Keywords naming_authority=gov.noaa.pfeg.coastwatch Northernmost_Northing=89.875 platform=Jason-2, Jason-3, Sentinel-3A, CryoSat-2, SARAL processing_level=L3 project=Radar Altimetry Database System reference=Leuliette, E.

该高度计数据源自RADS（http://rads.tudelft.nl/rads/rads.shtml），即雷达高度计数据库系统，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通过最先进的潮汐、大气路径延迟等校正进行更新。由于这些校正在不同任务之间均保持一致，因此避免了由于不同机构实施不同校正方法而引入偏差和漂移的可能性。RADS的目标是提供统一的海洋水位异常、波浪高度和风速数据集，并配备数据库选择和分析工具。数据类型：网格遵循规范：CF-1.6, COARDS, ACDD-1.3 处理算法：RADS 4.2.5 产品状态：实验性卫星：Jason-2, CryoSat-2, SARAL, Jason-3, Sentinel-3A 地理范围：最东经179.875度，最北纬89.875度，最南纬-89.875度，最西经-179.875度历史记录：雷达高度计数据库系统（RADS）数据数据源：ftp://ftp.star.nesdis.noaa.gov:/pub/socd/lsa/rads/sla/daily/nrt 数据标识：nesdisSSH1day 信息链接：https://coastwatch.noaa.gov/cw_html/SSH_SeaLevelAnomaly.html 机构：美国国家海洋和大气管理局/国家卫星应用和研究中心关键词词汇：GCMD 科学关键词命名机构：gov.noaa.pfeg.coastwatch 最北纬：89.875度最南纬：-89.875度时间范围结束：2024-06-27T00:00:00Z 时间分辨率：PD1 时间范围开始：2017-02-13T00:00:00Z
