Sensitivity Analysis of Brown Model Waveform in Radar Altimetry
In satellite altimetry (radar altimetry), the altimeter emits a pulse, with known power, to the earth surface and receives it back continuously to determine of the sea surface height. The time series of the mean returned power is recorded individually at satellite as the so-called waveform. Analytical model for the waveform is first introduced by Brown, which consists of six parameters: signif...
متن کاملRecent Deceleration of the Ice Elevation Change of Ecology Glacier (King George Island, Antarctica)
Glacier change studies in the Antarctic Peninsula region, despite their importance for global sea level rise, are commonly restricted to the investigation of frontal position changes. Here we present a long term (37 years; 1979–2016) study of ice elevation changes of the Ecology Glacier, King George Island (62◦11′S, 58◦29′W). The glacier covers an area of 5.21 km2 and is located close to the H....

متن کاملImpact of resolution and radar penetration on glacier elevation changes computed from DEM differencing
Digital elevation models (DEMs) are now frequently used to calculate elevation changes and regional mass balances of glaciers, for example in the Alps (Berthier and others, 2004; Paul and Haeberli, 2008; Huss and others, 2010), Alaska and Canada (Larsen and others, 2007; Schiefer and others, 2007; Berthier and others, 2010), Patagonia (Rignot and others, 2003) or High Mountain Asia (Surazakov a...
متن کاملRadar Altimetry of Mercury' A Preliminary Analysis
Measurements of Mercurian topography based on Arecibo radar observations are presented. The data, which were obtained from 1978 to 1984, cover much of the equatorial zone of Mercury between 12øN and 5øS latitude. Over thirty continuous altitude profiles were obtained, each spanning from 20 to 90 degrees of longitude at a resolution of 0.15 ø (longitude) by 2.5 ø (latitude). Radar depths for lar...
