Wood combustion and other biomass combustion represent renewable energy sources, and means to reduce global CO2 emissions if the biomass stems from sustainable agriculture and forestry. On the other hand, biomass combustion inherently produces high emissions of particulate matter. These aerosol particles exert a climate forcing and have adverse health effects. The strengths of both, climate and health effects, vary during the lifetime of the aerosol due to physicochemical aging processes in the atmosphere. In this project, physical and chemical properties of emissions caused by intended burning of biomass for the purpose of cooking and heating will be characterized comprehensively. The aerosol’s aging processes in the atmosphere and their effects on hygroscopic growth, on concomitant mobility, scattering and absorptivity, and on cloud formation will be studied by field measurements, laboratory investigations and modeling studies. These results will allow an assessment of their impact on air quality and climate. External costs of biomass burning emissions versus those of other sources of energy production will be assessed by means of an economic model.
