Satellite remote sensing observations and on-site observations on offshore platforms are currently the two most mainstream means of observing characteristics of marine aerosols. Among them, satellite remote sensing observations have the advantage of a wide range of observations, while on-site observations on offshore platforms can obtain observation data with higher time resolution, and have the advantages of easy calibration and maintenance, and high-quality observation data. By using the measured aerosol optical thickness data from the Calibration Validation Field Network of Autonomous Ocean Satellites in the North Yellow Sea, the main aerosol types and optical properties of the offshore station are discussed to provide theoretical and technical support for the calibration and validation of autonomous ocean satellites, as well as the commercial operation of autonomous calibration and validation field networks. Using data from January 2020-June 2023, the data were classified into six main aerosol types according to the graphical classification: clean, desert dust, continental, subcontinental, urban industrial and biomass burning aerosols, and the main aerosol particles at the stations were analyzed by the ESI, single scattering albedo and fine mode fraction. The results show that spring is the most polluted season among the four seasons in the area, continental-type aerosols dominate throughout the year, and the main aerosol type at the station is a continental type aerosol with weak and moderate absorption coarse particle mode.
