Black Carbon Measurements of Snow and Ice Using the Single Particle Soot Photometer: Method Development and an AD 1852-1999 Record of Atmospheric Black Carbon from a Mount Logan Ice Core
<p>Black carbon (BC), produced by the combustion of fossil and biofuels, warms the climate by absorbing solar radiation when in the atmosphere and by reducing the albedo of snow and ice when deposited. Measuring BC in snow and ice is important for estimating albedo reduction and developing …
