按纬度和季节划分的海洋二甲基硫排放量和大气气溶胶粒子群（凝结核，CN）似乎直接相关，因为在二甲基硫通量和入射太阳辐射高（或低）的区域，用凝结核计数器测量的CN高（或低）。虽然它以前已经假设，CN产生DMS 1，2，我们报告的第一次尝试，相关DMS通量和CN。由于海洋空气中云凝结核（CCN）的数量是CN数量的一个子集3，4，而CCN反过来又控制着海洋云的蒸发量5，6，DMS可以通过云蒸发量反馈机制参与气候控制。
Oceanic dimethylsulphide (DMS) emissions and atmospheric aerosol particle populations (condensation nuclei, CN), resolved by latitude and season, appear to be directly correlated, in that CN, as measured with a condensation nucleus counter, are high (or low) in regions where DMS fluxes and incident solar radiation are high (or low). Although it has been previously hypothesized that CN are produced from DMS1,2, we report the first attempt to correlate DMS flux and CN. As the population of cloud condensation nuclei (CCN) in marine air is a subset of the CN population3,4, and CCN in turn control the albedo of marine clouds5,6, DMS could be involved in climate control through a cloud albedo feedback mechanism.
