Marine gravity anomaly from Geosat and ERS 1 satellite altimetry

Closely spaced satellite altimeter profiles collected during the Geosat Geodetic Mission (∼6 km) and the ERS 1 Geodetic Phase (8 km) are easily converted to grids of vertical gravity gradient and gravity anomaly. The long‐wavelength radial orbit error is suppressed below the noise level of the altim... View More
