“This image was assembled from microwave data from the Special Sensor Microwave/Imager (SSM/I) of the Defense Meteorological Satellites Program. Snow and ice emit microwaves, but the signal is different for wet, melting snow than for dry. Marco Tedesco, a professor at the City College of New York, uses this difference to chart the number of days that snow is melting every year. This image above shows 2010 compared to the average number of melt days per year between 1979 and 2009.” Source: NASA-EO
Greenland Melting – Short Movie
A short movie of videos and stills from Greenland collected by Marco Tedesco and his team in their 2009 and 2010 expeditions. “The theme is: meltwater. You will see canyons through which water flows, supraglacial lakes and ice cracks routing surface water to the bottom of the ice sheet. The vocal background at the beginning is a Shaman Inuit Chant.”
