Short summary

This study quantitatively establishes simple-to-use correction factors for accurately estimating particle-phase light absorption properties from bulk-phase attenuation measurements of Teflon filter samples. Using contact-free optical instrumentation with a two-stream radiative transfer model, we developed a wavelength-independent empirical correction formulation by comparing filter attenuation of aerosol-laden Teflon filter samples with in situ light absorption for a range of real-world fuels.
