Carbonaceous Aerosols: Understanding Water Uptake and Effects on Light Absorption

Fossil fuels and biomass fuels emit carbonaceous aerosol (CAA), which can absorb solar radiation. Our research measures how water uptake affects the ability of these aerosols to absorb light. We also analyze the optical properties of wildfire smoke particles. Our new instrument, laboratory experiments, field observations and model parameterizations address critical gaps in understanding absorption data collected by ARM and help advance CAA treatments in E3SM. This will lead to better understanding of the radiative effects of aerosols and their impact on the Earth.
