TOPEX/Poseidon + Jason-1 + ERS-1/2 + Envisat mapped and gridded satellite altimeter data- Global 1 degree grid - 1992-2004

This data set contains mapped and gridded data from TOPEX/Poseidon (NASA/CNES), Jason-1 (CNES/NASA), ERS-1, ERS-2 and Envisat (ESA). At any given time data from all available satellites is included in the mapped and gridded data product. At times only data for TOPEX/Poseidon is available. This is indicated in one of the fields in the data file. Data comes from TOPEX/Poseidon and ERS-1/2 up until about June, 2003. After that data comes from the follow-on missions - Jason-1 and Envisat. The data is on a 1 degree Mercator grid - the longitude grid spacing is always 1 degree. The latitude grid spacing is 1 degree at the equator, but gets smaller with distance from the equator. This data set is in a relatively easy to use format. The data was provided by Aviso/CNES in France and has been reformatted into a netCDF file at CSIRO Marine Research in Hobart. Available on-line on the CSIRO Marine Research network; also available to outside users on request.

该数据集包含来自TOPEX/Poseidon（NASA/CNES）、Jason-1（CNES/NASA）、ERS-1、ERS-2以及Envisat（ESA）的映射与网格化数据。在任意给定时间点，所有可用卫星的数据均被纳入该映射与网格化数据产品中。有时仅TOPEX/Poseidon的数据可用，这一情况会在数据文件的某一字段中予以标识。截至2003年6月左右，数据来源于TOPEX/Poseidon和ERS-1/2；此后的数据则来自后续任务——Jason-1和Envisat。数据采用1度墨卡托网格（Mercator grid）；经度网格间距始终为1度，纬度网格间距在赤道处为1度，但随远离赤道而逐渐减小。该数据集采用相对易用的格式。数据由法国的Aviso/CNES提供，并在霍巴特的CSIRO海洋研究所（CSIRO Marine Research）重新格式化为netCDF文件。可通过CSIRO海洋研究所网络在线获取；外部用户亦可通过申请获取。
