C13F:
Dust, Black Carbon, and Other Aerosols in the Cryosphere Posters


Submit an Abstract to this Session


Session ID#: 51302

Session Description:
Observation and modeling efforts have established the powerful regional impact on snow and ice cover from the deposition of light absorbing aerosols, such as mineral dust, carbonaceous particles, and biological constituents.  The subsequent darkening of the snow surface and initiation of snow albedo feedbacks has implications for the global climate and water cycle. This session will focus on observations and modeling of the past, present, and future impacts of mineral dust, carbonaceous particles, biological constituents, and other aerosols on snow and ice cover including transport and deposition processes, optical properties, impacts to albedo and snowmelt, glacier/ice sheet mass balance, and atmospheric heating.
