Comparison of measured and calculated scattering from surface aerosols with an average, a size-dependent, and a time-dependent refractive index
Mid-continental surface aerosols have been measured at a small, minimally polluted city in summer and winter and on a nearby remote mountain in summer. Aerosol scattering, absorption, size distribution, and composition were measured using a three-wavelength nephelometer, an aethalometer, a passive cavity aerosol spectrometer, a scanning mobility particle sizer, an Aerodyne quadrupole aerosol mass spectrometer, and conventional filter systems. Size-dependent, time-dependent, and averaged refractive indices are estimated from the aerosol composition measurements and then used to calculate ...

Effects of near-source coagulation of biomass burning aerosols on global predictions of aerosol size distributions and implications for aerosol radiative effects Author(s):Ramnarine, Emily
Date Submitted:2018Biomass burning is a significant global source of aerosol number and mass. In fresh biomass burning plumes, aerosol coagulation reduces aerosol number and increases the median size of aerosol size distributions, impacting ...
