This work presents a triangle-shaped moored array dataset comprising three buoys and two moorings with synchronous atmospheric and oceanic data in the northern South China Sea during 2016. The moored array was deployed from late July to early August and recovered in October. The atmospheric data were observed by meteorological sensors and automatic meteorological stations ~2.5 m above sea surface at the buoys. The oceanic data consist of temperature and salinity measurements using conductivity, temperature, and depth (CTD) recorders or temperature sensors. It also includes currents observed by acoustic Doppler current profilers (ADCPs) and current meters. The data reveal air–sea interactions and oceanic processes in the upper and deep ocean. Multiscale processes were recorded, such as air–sea fluxes, tides, internal waves, and low-frequency flows and variations. The data are valuable and may have a lot of potential applications, including analyzing the phenomena and mechanisms of air–sea interactions and ocean dynamics as well as validating and improving numerical model simulations, data reanalysis, and data assimilation.
