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...
