Web20 de oct. de 2024 · Long-term measurements of atmospheric mass concentrations of black carbon (BC) are needed to investigate changes in its emission, transport, … WebBlack carbon (BC) is one of the light-absorbing particles that reduce the albedo of snow surfaces. Snow samples were taken from the surface of three glaciers in the Alaska Range in mid-April 2024. The BC size distribution and concentration were analyzed with a laser-induced incandescence (LII) method.
