First spaceborne observation of sea surface height using GPS-Reflectometry
An analysis of spaceborne Global Positioning System reflectometry (GPS-R) data from the TechDemoSat-1 (TDS-1) satellite is carried out to image the ocean sea surface height (SSH). An SSH estimation algorithm is applied to GPS-R delay waveforms over two regions in the South Atlantic and the North Pacific. Estimatesmade fromTDS-1 overpasses during a 6month period are aggregated to produce SSHmaps...
متن کاملNear-coastal satellite altimetry: Sea surface height variability in the North Sea – Baltic Sea area
The radiometer wet tropospheric correction is a limiting factor of the application of near-coastal altimetry observations in the North Sea – Baltic Sea area. Using an ECMWF model based correction instead, we increase the return rate from 70% to 95%, with observations as close as 10 km from the coast. The altimetry and 39 coastal tide gauges are referenced to the same state of the art regional g...
متن کاملArctic sea surface height variability and change from satellite radar altimetry and GRACE, 20032014
Arctic sea surface height (SSH) is poorly observed by radar altimeters due to the poor coverage of the polar oceans provided by conventional altimeter missions and because large areas are perpetually covered by sea ice, requiring specialized data processing. We utilize SSH estimates from both the icecovered and ice-free ocean to present monthly estimates of Arctic Dynamic Ocean Topography (DOT)...
متن کاملStochastic Dynamics of Sea Surface Height Variability
Sea surface height anomalies measured by the Ocean Topography Experiment (TOPEX)/Poseidon satellite altimeter indicate high values of skewness and kurtosis. Except in a few regions, including the Gulf Stream, the Kuroshio Extension, and the Agulhas Retroflection, that display bimodal patterns of sea surface height variability, kurtosis is uniformly greater than 1.5 times the squared skewness mi...
متن کاملA Rational Function Model Based Geo-Positioning Method for Satellite Images without Using Ground Control Points
Earth observation satellites with various spatial, spectral and temporal resolutions provide an invaluable means for mapping and monitoring the Earth’s environments. With the increasing demand of satellite images for remote and harsh environments and nature disaster areas such as earthquake, flooding, bushfires and other emergent events, quickly geo-positioning those images without using ground...
