Impact of soot deposited onto snow and ice surfaces in the Arctic Impact of soot deposited onto snow and ice surfaces in the Arctic. Polar ice reflects light from the sun back to space (a). As the ice begins to melt, less light is reflected and more is absorbed by [..]
Monthly averaged aerosol optical depth anomalies at Barrow for March and April Monthly averaged aerosol optical depth anomalies at Barrow (Alaska) for March and April. The anomalies are relative to a base of non-volcanic years. Data from 1992 and 1993 were removed due to [..]
