[1] This paper investigates the potential of low‐cost spaceborne data to approximate longitudinal surface profiles during flood events on large rivers. In February 2000, the Shuttle Radar Topography Mission (SRTM) measured the elevation of most of the Earth’s surface with spatially continuous sampling and an absolute vertical accuracy between 5.6 and 9 m. The vertical error has been shown to ch...

The electromagnetic bias (EM) is a critical error term in sea surface height estimation from satellite radar altimetry. At present the EM bias models used in current altimetry missions are empirically based and globally-averaged functions of the altimetermeasured signi cant wave height and wind speed alone. Recent studies have shown that a reduction in the EM bias error variance can be achieved...

Water level (WL) and water volume (WV) of surface-water bodies are among the most crucial variables used in water-resources assessment and management. They fluctuate as a result of climatic forcing, and they are considered as indicators of climatic impacts on water resources. Quantifying riverine WL and WV, however, usually requires the availability of timely and continuous in situ data, which ...

The surface topography of the Greenland and Antarctic ice sheets is the principal ice parameter obtainable from satellite radar altimetry. The improved ability of the GEOSA T altimeter to follow irregular surfaces and its extended operation have greatly increased the available topographic data on ice sheets for the study of ice dynamics and the possible detection of changes in global ice volume.

[1] Surface temperatures were extracted from nighttime thermal infrared imagery of 167 large inland water bodies distributed worldwide beginning in 1985 for the months July through September and January through March. Results indicate that the mean nighttime surface water temperature has been rapidly warming for the period 1985–2009 with an average rate of 0.045 ± 0.011°C yr and rates as high a...

Variations in surface water extent and storage are poorly characterized from regional to global scales. In this study, a multi-satellite approach is proposed to estimate the water stored in the floodplains of the Orinoco Basin at a monthly time-scale using remotely-sensed observations of surface water from the Global Inundation Extent Multi-Satellite (GIEMS) and stages from Envisat radar altime...
