Retracking CryoSat-2, Envisat and Jason-1 radar altimetry waveforms for improved gravity field recovery
S U M M A R Y Improving the accuracy of the marine gravity field requires both improved altimeter range precision and dense track coverage. After a hiatus of more than 15 yr, a wealth of suitable data is now available from the CryoSat-2, Envisat and Jason-1 satellites. The range precision of these data is significantly improved with respect to the conventional techniques used in operational oce...
متن کاملComparison of retracking algorithms using airborne radar and laser altimeter measurements of the Greenland ice sheet
-This paper compares four cont/nental ice sheet radar altimeter retracking algorithms using airborne radar and laser altimeter data taken over the Greenland ice sheet in 1991. The refurbished Advanced Application Flight Experiment (AAFE) airborne radar altimeter has a large range window and stores the entire return waveform during flight. Once the return waveforms are retracked, or post-process...
متن کاملApL D2p radar Altimeter over Land and sea ice
easuring changes in the cryosphere from satellite-based altimeters has and will continue to provide data that are essential to our understanding of the long-term trends of the earth’s ice cover. over the past years, ApL has played a major role in airborne field activities observing continental ice sheets, outlet glaciers, and sea ice using the delayDoppler phase-monopulse (D2p) airborne radar a...
متن کاملAnalysis of CryoSat’s radar altimeter waveforms over different Arctic sea ice regimes
Satellite altimetry has been used to derive information about sea ice thickness in the Arctic already for several decades. As part of the algorithms applied the shape of the radar signal is used to identify leads, the open water between ice floes. Analysis of airborne altimeter data reveals that the waveform shape can additionally be used to identify different sea ice types. In this study we an...
متن کاملArctic Sea Ice Thickness Estimation from CryoSat-2 Satellite Data Using Machine Learning-Based Lead Detection
Satellite altimeters have been used to monitor Arctic sea ice thickness since the early 2000s. In order to estimate sea ice thickness from satellite altimeter data, leads (i.e., cracks between ice floes) should first be identified for the calculation of sea ice freeboard. In this study, we proposed novel approaches for lead detection using two machine learning algorithms: decision trees and ran...
