The Atmospheric Transport of Major Aerosol Species Over The North Atlantic Ocean

该计划的重点是在海洋大气中发现的主要气溶胶物种：nss-SO4=，来自海洋中的人为来源和生物来源；MSA（甲烷磺酸盐），形式DMS（二甲基硫化物）源自海洋；来自人为来源、闪电和平流层的NO3-；NH4+，来自大陆和海洋；Na+，来自海盐。我们还（与罗德岛大学）研究了该地区大气中存在的矿物种类。主要目标是描述这些物种在海洋上的分布特征，并了解控制其浓度的因素；物种的来源及其时间和面积的变化；通过大气的传输路径和进入海洋的传输路径。

This program focuses on the major aerosol species that are found in the marine atmosphere: nss-SO4=, from anthropogenic sources and biological sources in the ocean; MSA (methanesulfonate), form DMS (dimethyl sulfide) derived from oceanic sources; NO3-, from anthropogenic sources, lightning and the stratosphere; NH4+, from continental and oceanic sources; Na+, from sea salts. We also study (with the University of Rhode Island) the mineral species present in the atmosphere in this region. The major objective is to characterize the distribution of these species over the ocean and to understand the factors that control their concentration; the sources of the species and their temporal and areal variability; the transport paths through the atmosphere and the removal to the ocean.
