| Zusammenfassung |
| Climatic effects of black carbon (BC) deposition on snow have been proposed
to result from reduced snow albedo and increased melt due to light-absorbing
particles. In this study, we hypothesize that BC may decrease the liquid-water retention capacity of melting snow, and present our first data, where
both the snow density and elemental carbon content were measured. In our
experiments, artificially added light-absorbing impurities decreased the
density of seasonally melting natural snow. No relationship was found in
case of natural non-melting snow. We also suggest three possible processes
that might lead to lower snow density. |
