updated map of ice sheet albedo decline

It’s been 1 month since I updated this map. I had to re-adjust the color scale from the earlier post to accomodate greater values. The 1-20 July, 2012 anomaly is off the scale for albedo change I had established in earlier examinations of data beginning in year 2000.

Map showing where the albedo reduction is greatest; the southern ‘saddle’ region, the peripheral low elevation areas, and the northwest.

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.
