Curtain plot for production of ozone from the ATom-1 campaign in the Atlantic. The 10 s air parcels are averaged into 10-degree latitude and 200 m altitude bins. Reactivities, such as P-O3, are calculated for each 10 s air parcel from the Modeling Data Stream (MDS), Version 2, using the UC Irvine chemistry-transport model (CTM) with HNO4 and PAN damped by thermal decomposition.

Figure 1. (a) Aerosol extinction calculated using Mie theory from composition-resolved size distributions plotted as a function of measured extinction from the SOAP cavity ring-down spectrometer during the ATom-4 campaign, showing representative error bars. (b) Calculated aerosol absorption and measured absorption from the SOAP photoacoustic spectrometer for cases when absorption >2 *10-6 m-1 (2x the detection limit).
