Tsunami detection by satellite altimetry [PDF]
Journal of Geophysical Research: Solid Earth, 1999 We present what is to our knowledge the first direct observation of the deformation of the surface of the ocean upon passage of a tsunami wave, on the high seas, far from the influence of shorelines and continental shelves. We use satellite altimetry data from the ERS‐1 and TOPEX/POSEIDON programs, complemented by spectrogram techniques and synthetic ...

Modeling Envisat RA-2 waveforms in the coastal zone: case-study of calm water contamination [PDF]
, 2010 Radar altimeters have so far had limited use in the coastal zone, the area with most societal impact. This is due to both lack of, or insufficient accuracy in the necessary corrections, and more complicated altimeter signals. This paper examines waveform
