Dimethyl sulfide(DMS) produced by marine phytoplankton is oxidized into sulfate aerosols and cloud condensation nuclei(CCN) in the atmosphere. Accurate measurement of the sea-air DMS flux by such as eddy correlation(EC) method is required to study the impact of DMS on the atmospheric chemistry and radiative processes. In this study, down-sized device for the EC method using fluorine-induced chemiluminescence was developed in order to be installed on the top of foremast of research vessels and to measure the DMS concentration fluctuation with high time resolution. After several performance tests, several observations in the marine air were carried out over the western North Pacific.

海洋浮游植物产生的二甲基硫(DMS)在大气中被氧化成硫酸盐气溶胶和云凝结核(CCN)。为了研究DMS对大气化学和辐射过程的影响，需要用涡旋相关(EC)等方法精确测量海-气DMS通量。在本研究中，为了安装在科考船的前部顶部，并以高时间分辨率测量DMS浓度波动，研制了一种用于电化学法的小型氟诱导化学发光装置。在几次性能测试之后，在西北太平洋的海洋空气中进行了几次观测。
