Aerosol measurements over the eastern China seas during 2017 to 2020

This dataset contains the concentrations of trace elements and water-soluble ions in total suspended particles (TSP) over the eastern China seas on four cruises during (1) 27 March – 14 April 2017 (spring), (2) 27 June – 19 July 2018 (summer), (3) 28 December 2019 – 17 January 2020 (winter), and (4) 12 – 29 October 2020 (autumn). The air mass exposure to chlorophyll a (AEC), air mass retention ratio over the land (RL), marine air mss retention ratio within the boundary layer (RMBL), and harmonic means of boundary layer height along the air mass trajectory (BLH_traj) corresponding to each TSP sample are also presented. The calculation code for these indices is available at https://doi.org/10.5281/zenodo.7056981.
