Satellite altimeter data from the radar altimeter on board the European ERS-2 satellite, comprising Global (81S -> 81N) sea surface height anomalies along ground tracks which are repeated every 35 days. There are two versions of this dataset. Each version is approximately 620 Mb and the period covered is May 1995 to July 2003. This data set is also known as "ERS-2, phase A", but there are no phases B, C,... One of the versions ("cor") has had a long-wavelength correction applied. The other version ("raw") has not had this correction applied. The data was provided by Aviso/CNES in France and has been reformatted at CSIRO Marine Research in Hobart to a uniform grid spacing and format. Available on-line on the CSIRO Marine Research network; also available to outside users on request.

Satellite altimeter data from the radar altimeter on board the European ERS-1 satellite, phase G, comprising Global (81S -> 81N) sea surface height anomalies along ground tracks which are repeated every 35 days. The dataset (which is combined online with phase C of the same mission) is approximately 190 Mb and the period covered is March 1995 to June 1996. The data was provided by Aviso/CNES in France and has been reformatted at CSIRO Marine Research in Hobart to a uniform grid spacing and format. Available on-line on the CSIRO Marine Research network; also available to outside users on request.

Satellite altimeter data from the GEOSAT (U.S. Navy Geosat radar altimeter satellite) Exact Repeat Mission, comprising Global (72S -> 72N) sea surface height anomalies along ground tracks which are repeated every 17 days. The dataset is approximately 220 Mb and the period covered is November 1986 to October 1989. The data was provided by NOAA/NGS in the USA and has been processed at CSIRO Marine Research in Hobart to a uniform grid spacing and format. Available on-line on the CSIRO Marine Research network; also available to outside users on request.

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.

Satellite altimeter data from the radar altimeter on board the European ERS-1 satellite, phase C, comprising Global (81S -> 81N) sea surface height anomalies along ground tracks which are repeated every 35 days. The dataset (which is combined online with phase G of the same mission) is approximately 190 Mb and the period covered is October 1992 to December 1993. The data was provided by Aviso/CNES in France and has been reformatted at CSIRO Marine Research in Hobart to a uniform grid spacing and format. Available on-line on the CSIRO Marine Research network; also available to outside users on request.

This data set contains mapped and gridded data from TOPEX/Poseidon (NASA/CNES), Jason-1 (CNES/NASA) and from 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. Up to about mid-2003 the data is from TOPEX/Poseidon and ERS-1/2. The next generation of satellites (Jason-1 and Envisat) take over after that. The data is on a 1/3rd degree Mercator grid - the longitude grid spacing is always 1/3rd degree. The latitude grid spacing is 1/3rd of a 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.

Satellite altimeter data from the radar altimeter on board the joint France/US Jason-1 Mission, comprising Global (66S -> 66N) sea surface height anomalies along ground tracks which are repeated every 10 days. The dataset is approximately 622 Mb and the period covered is January 2002 to January 2004. The data was provided by JPL/NASA in the USA and has been processed at CSIRO Marine Research in Hobart to a uniform grid spacing and format. Jason-1 is the follow-on mission to TOPEX/Poseidon. Available on-line on the CSIRO Marine Research network; also available to outside users on request.

Satellite altimeter data from the radar altimeter on board the joint US/France TOPEX/Poseidon Mission, comprising Global (66S -> 66N) sea surface height anomalies along ground tracks which are repeated every 10 days. The dataset is approximately 584 Mb and the period covered is September 1992 to August 2002. The data was provided by JPL/NASA in the USA and has been processed at CSIRO Marine Research in Hobart to a uniform grid spacing and format. Available on-line on the CSIRO Marine Research network; also available to outside users on request.

GFO is a radar altimeter used to measure ocean wave heights and currents. This data set covers the period from 07-Jan-2000 to 02-Jun-2008. The data set comprising near global (72S - 72N) sea surface height anomalies, the along ground tracks are repeated every 17 days and are the same the same ground track as GEOSAT. The data has been processed at CSIRO Marine Research in Hobart to a uniform grid spacing and format, there is one file for each satellite pass and the data files are in a simple binary format.. It is available on-line on the CSIRO Marine Research network; also available to outside users on request.

Envisat was launched in March 2002,by the European Space Agency, it is an advanced polar-orbiting Earth observation satellite which provides measurements of the atmosphere, ocean, land, and ice. This dataset comprises near global (81S - 81N) along ground tracks which are repeated every 35 days, covering the same track as the ERS-1 and ERS-2 satellites. The dataset period covered is June 2003 to January 2008. The data was provided by ESA in France and has been reformatted at CSIRO Marine Research in Hobart to a uniform grid spacing and format. Available on-line on the CSIRO Marine Research network; also available to outside users on request.
