Laser altimetry sampling strategies over sea ice
With the conclusion of the science phase of the Ice, Cloud and land Elevation Satellite (ICESat) mission in late 2009, and the planned launch of ICESat-2 in late 2015, NASA has recently established the IceBridge program to provide continuity between missions. A major goal of IceBridge is to obtain a sea-ice thickness time series via airborne surveys over the Arctic and Southern Oceans. Typicall...
متن کاملErs-envisat Tandem Cross-interferometry for Monitoring of Sea Ice
The very short temporal separation (about 28 minutes) of the ERS-2 and ENVISAT satellites is very attractive to obtain almost-simultaneous acquisitions, appealing for SAR Interferometric applications both for the very high temporal correlation, for the strong reduction of atmospheric artefacts, and for monitoring fast displacements. The problem of the interferometric combination of such data ar...
متن کاملErs – Envisat Tandem Data over Sea and Shelf Ice
ERS – ENVISAT Tandem (EET) data are SAR data pairs acquired by the ERS-2 and ENVISAT ASAR instruments from approximately the same orbits within 28 minutes. During two dedicated campaigns in 2007/2008 and 2008/2009 ESA specifically acquired EET pairs with baselines suited for cross-interferometry (CInSAR). At perpendicular baselines of about 2km the frequency difference and baseline effects on t...
متن کاملEnvisat and the Ice Conditions in the Baltic Sea
In this paper the Finnish ENVISAT CAL/VALproject as well as some results obtained in the project will be presented. The project has three major objectives. One objective is to implement an operational data processing chain, the other is to analyze the effect of different ice properties on the SAR signature and its statistics mainly through empirical backscatter studies, and the third is to deve...
متن کاملComparison of the Envisat Waveform Retrackers over Inland Waters
Since the launch of ENVISAT satellite in 2002, the Radar Altimetry Mission provides systematic altimeter observations of the Earth surface. The ENVISAT Geophysical Data Records products contain, over all type of surfaces, altimeter ranges derived from four specialized retrackers: Ocean, Ice-1, Ice-2 and Sea-Ice retracker. Among the different goals of the ENVISAT Mission, one directly concerns l...
