Short summary
Concentrations and fluxes of selected volatile organic compounds were measured over a 5-month period in central London as part of the ClearfLo project using a proton transfer reaction mass spectrometer. Emission sources within the city were inferred from spatio-temporal patterns and showed a detectable biogenic source during warmer months, which was modelled using the Guenther 95 algorithm. Comparisons were made with the local emissions inventories showing mostly underestimated emissions.
