Measurement report: Unexpected high volatile organic compounds emission from vehicles on the Tibetan Plateau Dataset

This dataset includes various emission profiles and related data, specifically: Source Profile Data at Different Altitudes. Emission Factor Data. Emission Ratio Data. Source Profile Data from PMF Source Apportionment: Data obtained through Positive Matrix Factorization (PMF), revealing the composition of emission sources. Average Profiles of Gasoline Vapors: Derived from sealed housing evaporative determination (SHED) tests, with references 1-7. Average Profiles of Gasoline Vehicle Exhaust: Based on dynamometer tests, with references 2, 8-13. Average Profiles of Vehicular Emissions: Collected from low-altitude tunnel measurements, reflecting emissions in real-world driving scenarios, with references 14-24.
