Raw Mass Spectrometry Measurements of Vehicle Exhaust Emissions under Real Driving Conditions

This dataset contains raw mass spectrometry (MS) data from off-line chemical analyses of vehicle exhaust emissions collected during Real Driving Emissions (RDE) measurements performed on certified routes in the Lyon metropolitan area (France) within the EASVOLEE project. The dataset includes measurements of low-, semi-, intermediate-, and volatile organic compounds (LVOCs, SVOCs, IVOCs, and VOCs). The raw analytical data are provided in their original vendor-specific MS format and can be processed using compatible software (e.g., Thermo Scientific Xcalibur). An accompanying Excel file describes the dataset structure and identifies the contents and locations of the individual data files. The dataset aims to characterize real-world emissions from representative European vehicle technologies and investigate emission events under typical operating conditions. The tested fleet covers a wide range of vehicle categories, fuel types, engine technologies, and Euro emission standards, enabling comparisons between legacy and modern vehicles under realistic driving conditions.
