Contributions

Y.N.M. proposed the fsLS-CUP of soot and PAHs. P.W. and Y.N.M. designed, built and characterized the fsLS-CUP system. P.W. and Y.N.M. performed the experiments. P.W. and Y.N.M. developed the image processing algorithm and conducted the image reconstruction. F.J.B. performed numerical modeling. Y.N.M., P.W., and F.J.B. analyzed the experimental data and drafted the manuscript. M.S.G. reviewed the technical details and advised on evaluation approaches. L.V.W. supervised the project. All authors revised the manuscript.
