This image of Greenland’s Jakobshavn Glacier (right) was acquired by Envisat’s Advanced Synthetic Aperture Radar (ASAR) instrument on 27 October 2010, just hours after reaching its new orbit.
The preliminary verification indicates that the ASAR instrument is delivering the same high-quality data as before the satellite's orbit was lowered from 800 km to 783 km, beginning on 22 October.
Jakobshavn, one of Greenland’s fastest moving glaciers, has been constantly observed by ESA’s Envisat and ERS-2 SAR instruments for the last 20 years. The size of the image is about 160 km by 90 km.
