Soot Content of Snow and Ice. Version 1.0

T. Grenfell, B. Light, M. Sturm & J. Holmgren
The presence of particulates in the snow cover and at the ice surface can decrease the spectral albedo of the system at visible wavelengths where absorption by ice and water is small. Because of this, we were concerned that the release and local deposition of soot particles from fuel burned onboard the ship could impact both albedos and melt rates. For additional documentation, start with the soot.htm file contained in the zip file html-metadata.zip.
