Fig. 1: Characteristics of the organic ions in the experimental forest.

From: Extensive urban air pollution footprint evidenced by submicron organic aerosols molecular composition

Fig. 1

a Time series profile of the daytime mass concentration of submicron OM, the sum of all ions from the thermal desorption analysis (TD-PTR-ToF-MS, all), and the sum of mass concentration of the 30 major ions indicated in Table 1. b Breakdown of the contribution of different mass ranges to the overall mass concentration of all the ions from MS and top 30 ions. c Size distribution profile (<1.0 μm) of the normalized concentration to the sum of mass concentration of major organic ions. The strong bold line indicates the average of all the tracers. Included in the graph are the size distribution profiles of the ions at 193 and 199 (dotted lines). The error bars represent the range of ±1 standard deviation.
