dc.description.abstract | The FIGAERO-CIMS (Filter Inlet for Gases and AEROsols + chemical ionization mass spectrometer) measures thermal desorption profiles for individual ions evolved from evaporation of organic aerosol components. Often, hundreds of individual thermograms are obtained, reflecting the compositional complexity of organic aerosol. We have developed a novel clustering algorithm, Noise-Sorted Scanning Clustering (NSSC), that provides a robust, reproducible analysis of the FIGAERO temperature-dependent mass spectral data. The NSSC allows for determination of thermal profiles for compositionally distinct clusters, increasing the accessibility and enhancing the interpretation of FIGAERO data. The potential of NSSC for analysis of FIGAERO-CIMS data is demonstrated via application to a suite of distinct experiments. A static version of the NSSC algorithm is archived here, and an evolving version at GitHub (doi: 10.5281/zenodo.3361796). The data used to test and develop the NSSC, and reported on in Li et al. (submitted to Atmospheric Measurement Techniques) and in Ziyue Li's dissertation at UC Davis, are archived here. The experiments took place at the Pacific Northwest National Laboratory. | |
