Smoke particle emissions from the combustion of biomass fuels typical for the western and southeastern United States were studied and compared under high humidity and ambient conditions in the laborat...
Effect of biomass burning on marine stratocumulus clouds off the California coast
biomass burning marine stratocumulus clouds California coast
2009/12/3
Aerosol-cloud interactions are considered to be one of the most important and least known forcings in the climate system. Biomass burning aerosols are of special interest due to their radiative impact...
Direct measurements of the effect of biomass burning over the Amazon on the atmospheric temperature profile
biomass burning Amazon atmospheric temperature profile
2009/11/19
Aerosols suspended in the atmosphere interact with solar radiation and clouds, thus change the radiation energy fluxes in the atmospheric column. In this paper we measure changes in the atmospheric te...
