Flight tracks for airborne campaigns in this dataset.
Dust mass observations across the Pacific Ocean made by the PALMS instrument combined with AMP aerosol size spectrometers during the ATom-4 campaign in May 2018.
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.

Photo of the interior of the PANTHER GC. This instrument was used during all ATom campaigns.
The CAPS instrument attached to the exterior of the NASA DC-8 aircraft.
Fire influences for air parcels on the ATom-2 research flight that occurred on 2017-02-15.

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).
