Publication abstract: The dependence of sea spray aerosol (SSA) particle number concentrations (Np) and size distributions on water temperature (Tw) over the range 2-25°C was quantified for particles generated from both a marine aerosol reference tank (MART) and a miniature MART (miniMART). Four water types were considered: NaCl water, reef salt (RS) water, filtered and autoclaved reef salt (FARS), and filtered but not autoclaved seawater (NASW). For NaCl, RS, and FARS water the Np exhibited a moderate, monotonic increase with Tw, with a sensitivity of 1.0 – 3.3% °C-1. This contrasts with some previous laboratory studies that used alternative generation methods but is consistent with determinations and parameterizations that are based on ambient observations. Complementary experiments using a continuous plunging jet with FARS water yield the same Tw dependence as MART and miniMART experiments suggesting that differences in particle generation method cannot explain the different results here compared to literature studies. The number-weighted size distributions here consisted of two modes. The larger mode exhibited a stronger Tw-dependence, although the overall shape was relatively insensitive to Tw. The Tw-sensitivity of Np for actual seawater (NASW) differed from the other water types, exhibiting complex, irreproducible behavior due most likely to temporally evolving seawater composition. These observations provide new constraints and context for understanding the dependence of SSA production on water temperature and composition.
