Cover Candidate for PNAS:
Albedo Decrease Linked to Arctic Sea Ice
These still images were generated to be cover candidates for the Proceedings of the National Academy of Sciences (PNAS). The images display data from the paper "Observational determination of albedo decrease caused by vanishing Arctic sea ice". Average September Arctic sea ice from 1979 is shown on the top globe of each image. Average September Arctic sea ice from 2012 with change in albedo overlaid is shown in the bottom globe of each image. Two images are provided which use different color tables.
This is the first study to document Arctic-wide decrease in planetary albedo using satellite radiation budget measurements and sea ice data. The study finds a very strong correlation between sea ice cover and planetary albedo.
