Graphitic Carbon in Urban Environments and the Arctic
The application of the Raman scattering, photoacoustic, optical attenuation, opticothermal analysis, and solvent extraction techniques to the characterization of the graphitic component of urban and remote aerosols will be described. These analyses allow unambiguous identification and quantification of the optically absorbing component of the aerosol. Recent observations in the Arctic show graphitic carbon concentrations which are comparable to those found in urban environments. The possible effects of these highly absorbing species on the heat balance will be discussed.
