Sampling periods ranged from 12 to 24 hours. The RH of the sampled air stream was measured a few inches upstream from the impactors. The 2-stage impactors cut the samples into submicrometer (Daero < 1.1 um at 60% RH), and supermicrometer (1.1 um < Daero < 10 um) samples. Aerosol mass size distributions from the 7-stage impactors (size cuts at: 0.18, 0.31, 0.55, 1.1, 2.0, 4.1 and 10 um) are available for download at: https://www.pmel.noaa.gov/acg/data/chemdist.php?cruise=ATOMIC. The impaction stage at the inlet of the impactor was coated with silicone grease to prevent the bounce of larger particles onto the downstream stages. Tedlar films were used as the collection substrate in the impaction stage and a Millipore Fluoropore filter (1.0-um pore size) was used for the backup filter. Films were cleaned in an ultrasonic bath in 10% H2O2 for 30 min, rinsed in distilled, deionized water, and dried in an NH3- and SO2-free glove box. Filters and films were wetted with 1 ml of spectral grade methanol and additional 5 ml of distilled deionized water were added to the solution and the substrates were extracted by sonicated for 30 min. For the 7 stage impactor (sizes 0.18, 0.31, 0.55 and 1.1), the extraction volume was reduced to 0.5mL:2.5mL methanol:water in later samples (12 and 15 through 27) to increase detection. The extracts were analyzed by ion chromatography [Quinn et al., 2000]. All handling of the substrates was done in the glove box. Blank levels were determined by loading an impactor with substrates but not drawing any air through it. Concentrations are reported as ug/m3 at STP (25C and 1 atm). Values below the detection limit are denoted with a zero and missing data are denoted with a NaN. Berner et al., Sci. Total Environ., 13, 245 - 261, 1979. Quinn et al., J. Geophys. Res., 105, 6785 - 6805, 2000. NOAA PMEL Gravimetrically-determined Aerosol Mass - collected with 2 stage impactors Two-stage multi-jet cascade impactors (Berner et al., 1979) sampling air at the indicated target sample RH were used to determine sub- and supermicron aerosol mass concentrations. The RH of the sampled air stream was measured a few inches upstream from the impactor. The 50% aerodynamic cutoff diameters, D50,aero, were 1.1 and 10 um. Submicron refers to particles with Daero < 1.1 um at 55% RH and supermicron refers to particles with 1.1 um < Daero < 10 um at 55% RH. The impaction stage at the inlet of the impactor was coated with silicone grease to prevent the bounce of larger particles onto the downstream stages. Millipore Fluoropore films were used as the collection substrate in the impaction stage and a Millipore Fluoropore filter (1.0-um pore size) was used for the backup filter. Films were cleaned in an ultrasonic bath in 10% H2O2 for 30 min, rinsed in distilled, deionized water, and dried in an NH3- and SO2-free glove box. Films and filters were weighed at PMEL with a Cahn Model 29 and Mettler UMT2 microbalance, respectively. The balances are housed in a glove box kept at a humidity of 65 ± 4%. The resulting mass concentrations from the gravimetric analysis include the water mass that is associated with the aerosol at 65% RH. The glove box was continually purged with room air that had passed through a scrubber of activated charcoal, potassium carbonate, and citric acid to remove gas phase organics, acids, and ammonia. Static charging, which can result in balance instabilities, was minimized by coating the walls of the glove box with a static dissipative polymer (Tech Spray, Inc.), placing an anti-static mat on the glove box floor, using anti-static gloves while handling the substrates, and exposing the substrates to a 210Po source to dissipate any charge that had built up on the substrates. Before and after sample collection, substrates were stored double-bagged with the outer bag containing citric acid to prevent absorption of gas phase ammonia. More details of the weighing procedure can be found in Quinn and Coffman [1998]. Concentrations are reported as ug/m3 at STP (25C and 1 atm). Berner et al., Sci. Total Environ., 13, 245 - 261, 1979. Quinn et al., J. Geophys. Res., 105, 6785 - 6805, 2000. Organic Carbon (Sunset Laboratory thermal/optical analyzer) Sub-1.1 um and sub-10 um samples were collected on pre-combusted quartz fiber filters using 2 and 1 stage impactors, respectively, for organic carbon (OC) and elemental carbon (EC) analysis [Bates et al., 2004]. A charcoal diffusion denuder was deployed upstream of the submicrometer impactor to remove gas phase organic species. OC and EC concentrations were determined with a Sunset Laboratory thermal/optical analyzer. Three temperature steps were used to evolve OC under O2-free conditions for quantification. The first step heated the filter to 230 Deg C; the second step heated the filter to 600 Deg C (AMS vaporizer temperature); and the final step heated the filter to 870 Deg C. After cooling the sample down to 550 Deg C, a He/O2 mixture was introduced and the sample was heated in four temperature steps to 910 Deg C to drive off EC. The transmission of light through the filter was measured to correct the observed EC for any OC that charred during the initial stages of heating. No correction was made for carbonate carbon so OC includes both organic and carbonate carbon. The percentage of carbonate carbon is unknown. Super-micrometer OC concentrations were determined by difference between submicrometer and sub-10 um impactor samples without denuders.
