Satellite - Altimetry calibration and validation

High precision satellite altimeter missions including TOPEX/Poseidon (T/P), Jason-1 and now OSTM/Jason-2, have contributed fundamental advances in our understanding of regional and global ocean circulation and its role in the Earth's climate and regional applications. These altimeter satellites essentially observe the height of the global oceans – as such, they have become the tool of choice for scientists to measure sea level rise – both at regional and global scales as well as giving information about ocean currents and large- and small-scale variability. The determination of changes in ...包括TOPEX/Poseidon（T/P）、Jason-1以及当前的OSTM/Jason-2在内的高精度卫星高度计任务，为我们理解区域与全球海洋环流及其在地球气候和区域应用中的作用带来了基础性重大进展。这类高度计卫星实质上对全球海洋表面高度开展观测——正因如此，它们已成为科学家测量区域及全球尺度海平面上升的首选工具，同时还能提供关于洋流、大尺度与小尺度海洋变率的相关信息。对……变化的测定
