Sea surface height measuring using InSAR altimeter

open access: yesGeodesy and Geodynamics, 2017
Satellite altimetry has been widely used in measuring ocean topography from space. The conventional altimeter system is the nadir radar altimeter system which has the limitations of one-dimensional measurement and is unable to get both high temporal and ...

Integrated SSA-LSTM-ARMA framework for sea-surface-height prediction [PDF]

open access: yesShandong kexue
With the increasing influence of global climate change on sea levels, accurate prediction of sea-surface-height variations is essential for marine environmental monitoring, disaster early warning, and coastal resource management. Using sea-surface-height

Impacts of mean dynamic topography on a regional ocean assimilation system [PDF]

open access: yesOcean Science, 2015
An ocean data assimilation system was developed for the Pacific–Indian oceans with the aim of assimilating altimetry data, sea surface temperature, and in situ measurements from Argo (Array for Real-time Geostrophic Oceanography), XBT (expendable ...

Sea surface height and steric height increases in the Southern Hemisphere [PDF]

open access: yesEos, Transactions American Geophysical Union, 2011
Sea surface height has increased by 3 millimeters per year, globally averaged, since 1993. Some fraction of sea surface height change is due to added water from melting glaciers, for instance, and some is due to increasing heat and salinity changes (steric effects).

Ocean Surface Anomalies after Strong Winds in the Western Mediterranean Sea

open access: yesJournal of Marine Science and Engineering, 2019
The Western Mediterranean Sea is often subject to intense winds, especially during the winter season. Intense winds induce surface cooling associated with anomalous ocean heat loss, upwelling and diapycnal mixing. In this study we investigate the overall

The sea surface height spectrum of internal waves

open access: yesJournal of Geophysical Research: Oceans
Internal waves and geostrophic motions contribute to sea surface height (SSH) variability at submesoscales. While geostrophic motions have a well-defined signature in SSH, the contribution from internal waves is small enough to be confounded with noise.
