The SWOT (Surface Water and Ocean Topography) Mission: Spaceborne Radar Interferometry for Oceanographic and Hydrological Applications
Satellite altimetry has revolutionized the study of the global oceans for the past two decades. Precision altimetry missions like TOPEX/Poseidon, Jason-1, and OSTM/Jason 2, complemented by other missions like ERS 1 and 2, ENVISAT, and GFO, have provided unprecedented observations of the ocean surface topography at scales larger than about 200 km and made significant advances in our understandi...
متن کاملOcean Surface Topography
Definition The deviation of the height of the ocean surface from the geoid is known as the ocean surface topography. The geoid is a surface on which the Earth’s gravity field is uniform. The ocean surface topography is caused by ocean waves, tides, currents, and the loading of atmospheric pressure. The main application of ocean surface topography is for the determination of large-scale ocean ci...
متن کاملAirborne Lidar Simulator for the Lidar Surface Topography (LIST) Mission
In 2007, the National Research Council (NRC) completed its first decadal survey for Earth science at the request of NASA, NOAA, and USGS.[1] The Lidar Surface Topography (LIST) mission is one of fifteen missions recommended by NRC, whose primary objectives are to map global topography and vegetation structure at 5 m spatial resolution, and to acquire global surface height mapping within a few y...
متن کاملImpact of Surface Waves on SWOT's Projected Ocean Accuracy
The Surface Water and Ocean Topography (SWOT) mission being considered by NASA has, as one of its main objectives, to measure ocean topography with centimeter scale accuracy over kilometer scale spatial resolution. This paper investigates the impact of ocean waves on SWOT’s projected performance. Several effects will be examined: volumetric decorrelation, aliasing of ocean waves, backscattering...
متن کاملGlobal Ocean Surface Vector Wind Observations from Space
The global ocean surface vector wind is a key climate and operational observation, achievable from proven space-borne scatterometer systems. Science and operational requirements for sampling frequency, record length, spatial resolution, and global coverage are described in a climate context, using explicit examples in physical oceanography and air-sea interactions. A loosely coordinated assembl...
