Mediterranean Sea level variations: Analysis of the satellite altimetric data, 1992–2008

Nonseasonal sea level variations in the Japan/East Sea from satellite altimeter data

[1] A merged TOPEX/POSEIDON and ERS-1/2 altimeter data set is used to estimate nonseasonal variations of sea surface height (SSH) in the Japan/East Sea (JES) from October 1992 through February 2002. The altimeter data have a good correlation (0.95) with tide gauge data in the western JES. The nonseasonal variability of the SSH is higher in the southern warm region than in the northern cold regi...

Energy characteristics of tidal and residual level variations in the Okhotsk Sea from satellite altimetry data

A unified satellite altimetry database, TOPEX/Poseidon (1993–2002) and Jason-1 (2002–2007) containing about 7,000 locations, was created for the Okhotsk Sea and adjacent areas. Amplitudes and phases of main tidal consituents were calculated for each location, and maps of tidal character and height were constructed. It is shown that diurnal waves dominate in the amphidromic areas of semidiurnal ...

Multi-Satellite Altimeter Data Analysis and Unification in the Mediterranean Sea

For long-term sea level variability studies a single altimetric mission of high accuracy and long duration is the ideal situation. In reality, several altimetric missions have been flown and the corresponding sea level heights present an increasing accuracy, mainly due to the improved orbital and geophysical corrections applied to the measured data. At least one different preprocessing is used ...

Statistical downscaling of GRACE gravity satellite-derived groundwater level data

With the continued threat from climate change, population growth and followed by increasing water demand, the need for hydrological data with high spatial resolution and proper time coverage to be felt more than ago. Therefore, having data such as terrestrial water storage changes and groundwater level changes with high resolution spatial helps to plan and make decisions for water resource mana...
