    "abstract": "This dataset contains number size distribution data from the University of Manchester Differential Mobility Particle Sizer (DMPS). The custom-built DMPS measured the evolution of size distribution for polydisperse particles formed from the ozonolysis of α-pinene (13/01/2020) or cresol (10/01/2020) in the Manchester aerosol chamber. Additionally, similar measurements were conducted under the same conditions but with black carbon (BC) as the seed (23/01/2020: BC + α-pinene; 22/01/2020: BC + cresol). These data were collected at the University of Manchester, between January and February 2020 as part of the Soot Aerodynamic Size Selection for Optical properties (SASSO) project. This information can reveal the evolution of the particles inside the chamber.\r\n\r\nThis version 0 dataset contains particle size distribution. The DMPS is operated by University of Manchester scientists.",
