Indonesian Throughflow Transport Variability Estimated Satellite Altimetry
2015/7/28
The relatively intense boundary currents of the western equatorial Pacific, as well as the western Pacific warm pool, have long been recognized as key components in the global climate system. More rec...
Hurricane Sandy Storm Surge Measured by Satellite Altimetry
Hurricane Sandy Storm Satellite Altimetry
2015/7/16
Hurricane Sandy made landfall on the East Coast of the United States around midnight UTC on October 30, 2012. What made this hurricane so devastating was the storm surge, which pushed water levels one...
Altimetry-observed semi-annual cycle in the South China Sea: Real signal or alias of K1 tidal error?
sea level semi-annual cycle satellite altimetry South China Sea
2009/11/17
There have been a number of applications of satellite altimetry to seasonal and interannual sea level variability in the South China Sea. However, these applications usually exclude shallow waters alo...
