ABSTRACT

The availability of large uniform highly reflective glacial ice areas with dry and clear atmospheric conditions near the location of Indian Antarctic station Maitri (Lat.70°45′S, Long.11°44′E) has been exploited to undertake spectro-radiometric measurements of snow-ice surfaces from the ground and from helicopter-mounted instruments with an aim to undertake vicarious calibration of an advanced wide field sensor (AWiFS) on board India's Resoursat-1 satellite. Consistent good-quality ground-truth data were collected at Sankalp Point near Maitri, concurrent with satellite overpasses on several cloud-free days during the 26th Indian Antarctic Expedition between November 21, 2006, and April 07, 2007. This paper describes the instruments, the experimental campaign, and the nature of data collected. Some aspects of the preliminary analysis undertaken and future plans are discussed.
