Sandwell Satellite Gravity Data

Stacked global satellite gravity profiles.

Sandwell satellite gravity data.

The satellite altimetry data from cryosat 2 is being provided by esa while data from the jason 1 mission was provided by the national aeronautics and space administration nasa and the centre national d études spatiales cnes. The data were developed by professor david t. Ftp plots for 36 hp plotter. The maps below have been sectioned into 16 clickable regions.

White paper in support of a high resolution ocean altimeter mission. Satellite data reveal formerly unknown tectonics structures. Send me an e mail dsandwell ucsd edu. 1957 1962 26 sept 1997.

Marine gravity from satellite altimetr. Our 2004 solution the dnsc08 solution from the danish national space centre 2008 and sandwell smith v16 1 2004. This satellite altimeter data base contains precise geoid and gravity anomaly profiles which were constructed from the average of 66 repeat cycles of geosat. Sandwell at the university of california in san diego.

If you would like to contribute data to the next version of the global topography grid we would be pleased to use it. Yale mm sandwell dt. We also incorporated data from the following missions. Ftp gmt scripts to create global.

Ftp the raw gravity data 1 minute grid 540mbytes exploring the ocean basins with satellite altimeter data. Ftp digital gridded topography data at 1 minute. Envisat esa ers 1 2 esa and geosat us navy. In 2008 we generated a version of satellite gravity we termed the trident solution by stacking three independently derived solutions of free air gravity from the geosat and ers 1 satellites.

The gravity field of the indian ocean west of australia based on the new satellite derived gravity model. Each dataset contains documentation including source contributor. Note that odd values of topography e g 2001m are constrained by actual soundings while even values e g 2000m are predicted from gravity. All marine bathymetry data are welcome.

Get ascii xyz topography at 1 minute. Data parameters include latitude longitude observed gravity and elevation bouguer gravity anomaly land and free air anomaly ocean. Any format is welcome even raw multibeam formats. Therefore one can extract the locations of the ship sounding.
