Ground-based component for SLCFs
Lead: Andreas Massling, AU

The objectives of this WP are

  • to develop a comprehensive data set on in-situ concentration of SLCF, column integrated parameters and
    particularly black carbon impacts on snow optical characteristics,
  • to plan future field study activities in Arctic areas and promote synergetic effects so that their interactions
    will be most sufficient to create and transfer new knowledge
  • to pilot near-real time delivery (NRT) from Arctic observation site,
  • to facilitate integration and harmonization of existing data sets and data streams,
  • to address observational gaps, in particular in relation to polar night measurements and effects of pollution
    on surface albedo and on radiative budget,
  • to perform comprehensive aerosol source apportionment particularly for the organic aerosols.
