Our 2004 solution the dnsc08 solution from the danish national space centre 2008 and sandwell smith v16 1 2004. Ftp digital gridded topography data at 1 minute.

Ftp plots for 36 hp plotter. Marine gravity from satellite altimetr. The view is towards the west. Ftp gmt scripts to create global.

We also incorporated data from the following missions. Satellite data reveal formerly unknown tectonics structures. Get ascii xyz topography at 1 minute. White paper in support of a high resolution ocean altimeter mission.

Note that odd values of topography e g 2001m are constrained by actual soundings while even values e g 2000m are predicted from gravity. 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. Sandwell at the university of california in san diego. Envisat esa ers 1 2 esa and geosat us navy.

Any format is welcome even raw multibeam formats. Stacked global satellite gravity profiles. Get ascii file of gravity anomaly or topography. Send me an e mail dsandwell ucsd edu.

Yale mm sandwell dt. The research is discussed in a related paper in science. The maps below have been sectioned into 16 clickable regions. This satellite altimeter data base contains precise geoid and gravity anomaly profiles which were constructed from the average of 66 repeat cycles of geosat.

Therefore one can extract the locations of the ship sounding. Ftp the raw gravity data 1 minute grid 540mbytes exploring the ocean basins with satellite altimeter data. The data were developed by professor david t. If you would like to contribute data to the next version of the global topography grid we would be pleased to use it.

Data parameters include latitude longitude observed gravity and elevation bouguer gravity anomaly land and free air anomaly ocean. 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.
