Datasets for "Comparison of the LEO and CPMA-SP2 techniques for black-carbon mixing-state measurements" Paper Details Title: Comparison of the LEO and CPMA-SP2 techniques for black-carbon mixing-state measurements Authors: Arash Naseri, Joel C. Corbin, Jason S. Olfert Affiliation: Department of Mechanical Engineering, University of Alberta, Edmonton, Alberta, Canada Metrology Research Centre, National Research Council Canada, Ottawa, Ontario, Canada Correspondence: Arash Naseri (arash@ualberta.ca) Accepted: 2 April 2024 Published: [Date] Purpose The purpose of providing these datasets is to enhance clarity and reproducibility of the results presented in the paper. By making the data available, we aim to facilitate further research, enable verification of our findings, and support transparency in the scientific process. Measurement Details Location: Kamloops, British Columbia, Canada (50°39'58.4"N, 120°21'45.5"W) Nearby Air Quality Station: 2.2 km away Nearby Highway: 0.7 km from the Trans-Canada highway Experiment Dates: 21 and 22 July 2021 Dataset Descriptions Case I Time Period: 21 July, 11:54 to 13:44 LT PM2.5 Concentrations: 1.7 to 4 μg/m³ Description: Low concentrations of mostly thinly coated rBC particles, presumably due to urban and highway emissions, and possibly some wildfire smoke. Case II Time Period: 22 July, 11:31 to 12:41 LT PM2.5 Concentrations: 10 to 81 μg/m³ Description: Moderate concentrations with a mixture of thinly and thickly coated rBC particles due to urban emissions and nearby forest fires. Case III Time Period: 22 July, 10:23 to 11:29 LT PM2.5 Concentrations: 122 to 104 μg/m³ Description: High concentrations with mostly thickly coated rBC particles due to wildfire smoke. Code Availability The MATLAB code used to generate the CPMA-SP2 results is publicly available at https://github.com/tsipkens/bidias. This code is specifically designed to invert tandem aerosol measurments, particularly in this paper CPMA-SP2 measurements to find two-dimensional size distributions. For generating SP2-LEO and Lagtime analysis, the SP2 toolkit version 4.118 was used. This toolkit is also publicly accessible and can be found at https://zenodo.org/records/3575186.
