updated map of ice sheet albedo decline
by Jason Box, meltfactor blog, July 25, 2012
It’s been 1 month since I updated this map. I had to re-adjust the color scale from the earlier post to accommodate greater values. The July 1-20, 2012, anomaly is off the scale for the albedo change I had established in earlier examinations of data beginning in year 2000.
Averaged over the whole of the ice sheet, for nearly 2 months now, the ice sheet albedo has been ~2 standard deviations below the 2000-2012 average.
Earlier blog entries discuss these albedo visualizations; here, here and here.
