Received: 16 Jan 2013 – Published in The Cryosphere Discuss.: 18 Feb 2013 Abstract. A simple analytical equation for the snow albedo as the function of snow
grain size, soot concentration, and soot mass absorption coefficient is
presented. This simple equation can be used in climate models to assess the
influence of snow pollution on snow albedo. It is shown that the squared
logarithm of the albedo (in the visible) is directly proportional to the
soot concentration. A new method of the determination of the soot mass
absorption coefficient in snow is proposed. The equations derived are
applied to a dusty snow layer as well.
