Short summary
This work presents time-resolved data of non-methane hydrocarbons (NMHC) from automatic chromatographs, measured over a period of 5 months in the greater Athens area. The measured concentrations are higher relative to other recent studies for the majority of NMHCs. A remarkable day-to-day variability is also observed. The contributions from traffic and residential heating to NMHCs are investigated, as they were the major sources impacting the air quality during the study period.
