Atmospheric Aerosols

Atmospheric Aerosols

ETA's atmospheric aerosol research seeks to understand the air quality and climate impacts of particles in the atmosphere. Ongoing research topics include:

  • The impact of black carbon on the albedo and melting of snow and ice in laboratory and field measurements
  • Indoor air quality and climate impacts of improved cookstove technology in developing regions
  • The effect of aerosol mixing state on aerosol single scattering albedo and black carbon absorption cross-section
  • Evaluation of black carbon and aerosol light-absorption measurement techniques
  • Trends in pollutant emissions from gasoline and diesel-powered motor vehicles, and changes in response to emission control technologies and fuel reformulation
  • Historical trends in black carbon concentrations in the atmosphere inferred from proxy data
