Reconstructed sea-surface heights for 1950 to 2001 as described in Church et al. (2004), except that it has been extended to the end of 2001. Briefly, this data set is: - near-global (65°S to 65°N) from January 1950 to December 2001 on a 1° × 1° × 1 month grid - seasonal signal removed - inverse barometer correction made - GIA (Mitrovica) correction made to tide gauge data
This file contains the monthly Global Mean Sea Level (GMSL) time series as shown on figure 2 of Church and White (2006). The sea level was reconstructed as described in Church et al (2004).
This data file contains global-mean thermosteric sea level anomalies and associated errors between 1950 and 2003, based on the enact 3 data set with Wijffels et.al. (2008) fall rate corrections applied to the eXpendable BathyThermograph (XBT). There are two files, one with yearly averages, the other with three-year running means. The Units are millimetres. For the errors, One-sigma error in the same units as the variables, and the period is 1950 to 2003, relative to 1961 (zero-crossing), the yearly averages are averages over a calendar year. The time in the file is the centre of the year averaged over. Three-year means are also centred on the time shown. and the depth-integrations are 0-100 m, 0-300 m, and 0-700 m. The three-year running means are as plotted in Domingues et.al. (2008), and are recommended as being the best to use.
This data file contains Ocean heat content (OHC) anomalies and associated errors between 1950 and 2003, based on the enact 3 data set with Wijffels et.al. (2008) fall rate corrections applied to the eXpendable BathyThermograph (XBT). There are two files, one with yearly averages, the other with three-year running means. The Units are: Joules X 1e-22 (i.e. multiply the numbers in the file by 1e22 to get OHC in Joules). For the errors, One-sigma error in the same units as the variables. and the period is 1950 to 2003, relative to 1961 (zero-crossing), the yearly averages are averages over a calendar year. The time in the file is the centre of the year averaged over. Three-year means are also centred on the time shown. and the depth-integrations are 0-100 m, 0-300 m, and 0-700 m. The three-year running means are as plotted in Domingues et.al. (2008), and are recommended as being the best to use.
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.

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.
