Above three images are (a) RGB true color image, (b) cloud and snow/ice classification image, and (c) brightness temperature image of snow area of the Antarctic, respectively. Antarctic ice sheet was observed from the Antarctic Peninsula to the Ross Ice Shelf (Image (a)). Snow over land, snow over sea ice, and clouds in the true color image are classified and shown in red, pink, and grey colors, respectively (Image (b)). You can see temperature variation (blue = cold, red = warm) resulted from the spatial variation of ice sheet thickness from 0 m to 3000 m (Image (c)).
These images are GLI 1km resolution images acquired on January 25 2003. The image (a) is GLI bands 13 (678nm), 8 (545nm), 5 (460nm) RGB true color image and the image (c) uses band 35 (11 µm) in the thermal infrared wavelength region.
