Abstract

New particle formation in a tropical marine boundary layer setting was characterized during NASA's Pacific Exploratory Mission–Tropics A program. It represents the clearest demonstration to date of aerosol nucleation and growth being linked to the natural marine sulfur cycle. This conclusion was based on real-time observations of dimethylsulfide, sulfur dioxide, sulfuric acid (gas), hydroxide, ozone, temperature, relative humidity, aerosol size and number distribution, and total aerosol surface area. Classic binary nucleation theory predicts no nucleation under the observed marine boundary layer conditions.

  16. Major aerosol instruments consisted of CN with diameters Dp > 10 nm (TSI 3760) UCN with diameters Dp >3 nm (TSI 3025) radial differential mobility analyzer (RDMA) size distribution Dp 8 to 250 nm and a laser optical particle counter (OPC-PMS LAS-X) size distribution Dp 150 to 7000 nm. RDMA dry surface areas at about 25% RH can be multiplied by about 3 to estimate ambient surface areas at 94% RH.
  17. Measurements of OH and H 2 SO 4 were recorded on a selected-ion chemical-ionization mass spectrometer [

  19. ; ibid. 98 9001 (1993)]. Two sigma uncertainties on individual 1-s measurements of H 2 SO 4 are ±42% (precision is 20%) but are much reduced for the 15-s averages used here [

  21. ]. SO 2 and DMS measurements were made with an isotopic-dilution gas-chromatography mass spectrometer [A. Bandy et al. ibid. 98 23423 (1993)]. The photochemically related parameters CO H 2 O NO O 3 NMHCs and UV irradiance were continuously recorded as were the meteorological parameters RH and T ; for details see (J. Hoell et al. ibid. in press). The above species and parameters were typically measured and averaged over times ranging from 15 s to 5 min. A subset of these (for example vertical and horizontal winds dew point and temperature) was high-resolution 20-Hz data.
  22. The time-dependent photochemical box model for diel trends in OH is similar to that described by D. Davis et al. [ J. Geophys. Res. 101 211 (1996)] and J. Crawford et al. [ ibid. 102 28447 (1997)]. The chemical model assumed all calculated species to be in photochemical equilibrium and included 50 standard HOx-NOx-CH 4 reactions 118 NMHC reactions 15 photolytic reactions and heterogeneous removal of soluble species. It was constrained by input values for O 3 CO CH 4 NMHCs NO H 2 O temperature pressure and when available measurements of the longer lived species H 2 O 2 CH 3 OOH HNO 3 and peroxyacetyl nitrate. Photolysis rates were calculated with the National Center for Atmospheric Research community radiative transfer code configured for four-stream DISORT calculations. Calculated J values were scaled for cloud effects based on a comparison of the observed OH with model estimated values (typically 10%).

  25. The DMS flux was estimated by using a mass conservation equation with measured DMS and OH values and model-generated diel profiles for NO 3 — d [DMS]/ dt = FDMS/EMD − (kOH[OH] + kNO 3 [NO 3 ]) [DMS]. The first term on the right-hand side is the DMS source term (sea-to-air flux) which depends on the oxidation rate of DMS and the equivalent mixing depth (EMD) (19 20). The latter can be viewed as the height of an atmospheric column that contains all DMS mass (both buffer and boundary layers) but at BL concentrations. The DMS oceanic flux is balanced by a comparable loss by reaction with OH and NO 3 calculated from the 24-hour profiles for DMS OH and NO 3 . For flight 19 the OH profile was generated independently from an O 3 /HOx/NOx/CH 4 photochemical box model constrained both by the measured photochemical controlling parameters O 3 H 2 O CO NO NMHCs UV and T and by the limited in situ BL OH measurements (18). Evaluation of the EMD (1.3 km for flight 19) was based on the vertical concentration data for DMS and CH 3 I (17 31). Using our estimated BL height of 0.6 km about half the DMS released had been transported into the overlying cloud layer and lower free troposphere.

  30. The sulfur model used in this study is similar to that previously described (17 19 31) and is based on 14 sulfur reaction processes five having two or more branches. Coupled sets of time-dependent continuity equations (with parameterized transport terms) are integrated to yield time-dependent concentration profiles of sulfur species. The general form of this equation is: d [S] BL / dt = Fsa / h + M / h × ([S] BuL − [S] BL ) + P(S) − L(S)[S] BL − k(SL)[S] BL . Here [S] BL represents the BL concentration of a given sulfur species (DMS SO 2 MSA H 2 SO 4 ) [S] BuL is the concentration of the sulfur species in the buffer layer Fsa is the sea-to-air flux of S (DMS) h is the marine BL height M is the mixing parameter where M = K / z P(S) is the photochemical production of sulfur species S L(S) is the photochemical loss of sulfur species S and k(SL) is the removal of S via aerosol (dry and wet) scavenging or dry deposition. The aerosol sticking coefficient for H 2 SO 4 (20) was derived from data collected near Christmas Island in the tropical Pacific during P3-B mission 7 of PEMT.

  40. The growth times for new nuclei over marine regions have been shown (37) to be inversely proportional to H 2 SO 4 (g) and α. It was also shown that for a fixed H 2 SO 4 (g) source strength the growth rate is independent of α because H 2 SO 4 (g) is inversely proportional to α. Because H 2 SO 4 (g) and its variation at the time of nucleation is unknown we have used a range of α to provide a plausible range of growth times.
