Abstract

The invention relates to a device for measuring, in near-real-time, the level of black carbon, brown carbon, organic carbon, total carbon and COin air. The device also provides for a direct calculation of aerosol angstrom coefficient as well as estimation of emissions rates of black carbon or brown carbon from nearby combustion sources.
