Fig. 1: Trends in concentration, composition, and sources of submicron aerosol in five self-concentrating pollution events in suburban Dublin.
From: Air quality—climate forcing double whammy from domestic firelighters
Time series of a PM1 components, measured in suburban Dublin from 28 November to 4 December 2016 (full measurements are available in the supplementary). Inset pie charts are the relative fraction of the chemical composition in PM1 during pollution episodes (i.e., Ep 1, 2, 3, 4, and 5). The values above the pie charts are the PM1 concentration in each episode; b OA factors and the relative fraction of OA factors in episodes; and c BC factors and the relative contribution of BC factors in episodes. BC data was averaged to 30 min from the original time resolution of 1 min to match the time stamp of ACSM.
