This field campaign will address multiple uncertainties in aerosol intensive properties, which are poorly represented in climate models, by means of aircraft measurements in biomass burning plumes. Key topics to be investigated are: Aerosol mixing state and morphology Mass absorption coefficients (MACs) Chemical composition of non-refractory material associated with light-absorbing carbon (LAC) Production rate of secondary organic aerosol (SOA) Microphysical processes relevant to determining aerosol size distributions and single scattering albedo (SSA) CCN activity.
