Dataset for "Measurement report: Investigation of Optical Properties of Different Fuels Diesel Exhaust by an Atmospheric Simulation Chamber experiment"
Description
This study examines optical properties and the variability of the mass absorption coefficient of carbonaceous aerosols produced by the combustion of different fuels. Experiments, conducted in an atmospheric simulation chamber, tested different methods of sampling and analyzing carbonaceous aerosols, with a focus on workplace environments. The dataset includes: • Continuous monitoring data of temperature, pressure, and humidity in ChAMBRe during each experiment. • Particle concentration and size distribution measured inside ChAMBRe using an SMPS. • Soot particle absorption coefficients (babs) at 870 nm from online measurements using a PAX from Droplet Measurement Technologies. • Soot particle absorption coefficients (babs) at 635 nm from online measurements using a Giano_BC1 from Dadolab srl. • Soot particle absorption coefficients (babs) from offline MWAA analysis at 635 and 850 nm on sampled filters. • EC and OC mass concentrations determined by TOT analysis using a Sunset EC/OC analyzer and the NIOSH 5040 protocol.

Steps to reproduce
Experiments were conducted at the ChAMBRe (Chamber for Aerosol Modelling and Bio-aerosol Research) facility, located in the Physics Department of the University of Genoa and managed jointly with the Genoa Division of the National Institute of Nuclear Physics (INFN). Ten experiments were performed to investigate the properties of carbonaceous aerosols and observe changes in the mass absorption coefficient (MAC) by varying fuel types and combustion conditions. Soot particles were introduced into ChAMBRe, monitored using online instruments, and sampled for offline analysis to study their concentration, size distribution, and optical properties. Both optical and thermal-optical techniques were employed to determine the MAC of the generated particles. All the details about methods and protocols to handle data are fully described in the related article.
