Black carbon (BC) emitted from incomplete combustions of fossil fuels and biomass is likely the second strongest positive climate forcer next to the carbon dioxide. Uncertainties in calculations of global and local radiative forcing of BC are still considerably large compared to the greenhouse gases, partly because of incomplete observational understandings and unpredictability of microphysical properties of aerosols containing BC and their efficiency of the wet removal during the cloud-precipitation processes.This paper reviews the principle and applications of the single-particle laser-induced incandescence technique, a recently developed method for fast real-time measurements of the detailed properties of individual particles containing BC. Most importantly, single-particle BC mass observable by this technique can be regarded as a tracer of BC-containing particles in an air parcel, providing a novel method to explore the possible difference in wet removal efficiency among particles with different microphysical properties. Finally, future perspectives of black carbon studies are briefly given.
