The mean seasonal cycle in sea ice surface albedo during 2000–2011 derived from the CERES data in the region 80–90°N (blue line) and from in situ surface albedo measurements from the Surface Heat Budget of the Arctic (SHEBA) project (18) of 1997–1998 (black line). Blue error bars indicate one SD of CERES 2000–2011 year-to-year variability, and gray shading indicates one SD of SHEBA spatial variability along a 200-m survey line.
