a Mass ratio of SO42−/NO3− as a function of RH. The circles are colored according to NO2 concentration, and circle sizes are scaled to LWC. b Gaseous HONO as a function of the sum of Naged EC-containing and NFe-rich from Jan. 21 to 26 covering Ep I and II. The circles are colored and sized according to LWC and SO42−, respectively. c The ratio of [SO42−]/([SO42−] + [SO2]) as a function of Naged EC-containing throughout the campaign. The circles are colored and sized according to LWC and NO2, respectively. d The ratio of [SO42−]/([SO42−] + [SO2]) as a function of NFe-rich from Jan. 21 to 26. The circles are colored and sized according to LWC and NFe-oxalate, respectively.
