Title: Formation of Refractory Black Carbon by SP2-Induced Charring of Organic Aerosol

Abstract

Black carbon (BC) in the atmosphere continues to be a focus of research because its lightabsorptive properties put it second only to CO2 as a warming agent of Earth's climate. Towards this end, the measurement of ambient BC has been aided greatly by the development of the Single Particle Soot Photometer (SP2) – an instrument that detects refractory black carbon (rBC) through laser-induced incandescence (Schwarz et al., 2006). Potential interference from other substances that can incandesce under 1064 nm illumination (e.g., some metals and minerals) is mitigated through the use of spectral bandpass filters (color temperature) to ensure that the SP2 remains highly selective to rBC. Here in this paper, we report on the detection of rBC that is produced through SP2 laser-induced charring (i.e., carbonization) of organic aerosols. Nigrosin – a non-BC-containing material – was used as a surrogate for light absorbing organic aerosols. The color temperature of the detected particles originating from charred nigrosin is near that of carbon black, fullerene soot, and ethylene soot, indicating that it is rBC. In conclusion, failure to properly account for this heretofore unidentified source of rBC will lead to an overestimate of rBC loadings, which could, in turn, impact aerosol radiativemore » forcing model predictions.« less
