RETRIEVING BLACK CARBON ON SNOW AND ICE SURFACES IN THE ARCTIC

Abstract

In the last IPCC report the black carbon (BC) impact of the Arctic was recognized as an independent and recognizable contribution to global climate change. The overall objective of the project behind the work presented here is to determine whether the black carbon content in snow and glacier ice surfaces can be retrieved from satellite data. Preliminary analysis of satellite measurements shows that high concentrations of BC (from local sources) are clearly detectable in the satellite signal, both over snow and glacier ice surfaces. Chemical BC analysis of snow and ice samples taken in the field show values consistent with the satellite data. Even if the general low BC level in the snow due to long-transported aerosols might be hard to measure in the cold, dry season, we have seen a significant increase in the signal during the melting which may make BC retrieval possible during the summer months. 1
