Absorption properties and graphitic carbon emission factors of forest fire aerosols

Data on the optical absorption properties (expressed as a specific absorption, B a ) of the smoke emissions from fires with forest fuels have been determined for a series of low‐intensity field fires and a series of laboratory scale fires. The B a data have been used to estimate the emission factors for graphitic carbon [EF(C e )] for these test fires to provide data needed for regional visibility studies, tropospheric air chemistry studies, and studies evaluating nuclear winter scenarios.
