英文摘要
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.
