January 2005 ASAR GMM Antarctic mosaic

This view of the entire continent of Antarctica is a mosaic of Envisat ASAR Global Monitoring Mode images acquired between 1 and 10 January 2005. The Ross Ice Shelf and McMurdo Sound are at the bottom side of the image. Working in GMM, the ASAR nstrument can provide regular information on areas such as Antarctica where, due to constant cloud cover, the use of optical data is unable to support scientific investigations.
