Dataset for the project "Particle size-resolved light absorption enhancement of black carbon: theory, instrumentation, and implications on climate"

Dataset Description This dataset was generated during the research project “Particle size-resolved light absorption enhancement of black carbon: theory, instrumentation, and implications on climate.” The data are divided into two separate archives, each corresponding to a published study associated with the project. 1. Validation of cantilever-enhanced photoacoustic particle-size-resolved light absorption measurement using nigrosin reference particles and Mie modelling (.zip)This archive includes raw light absorption data measured with the DMA–CEPAS system and particle number concentration data measured with a CPC. The dataset consists of multiple days of measurements using monodisperse nigrosin aerosol particles. Details of the optical properties and modelling approach are provided in the corresponding publication. 2. Experimental investigation of soot morphological transformation and its impact on size-resolved light absorption (.zip)This archive contains both raw and MATLAB-processed data, including light absorption (DMA–CEPAS), particle number concentration (CPC), and particle mass (CPMA) measurements. A log file is also provided, documenting the sampling system settings and operational parameters for each measurement day.
