Aerosol methansulfonic acid (MSA) over coastal East China Sea and the Gulf of Aqaba

These data were obtained by offline sampling and ion chromatography determination. The sampling time of each sample is also given in this dataset.

Other parameters include the air mass retention ratio over the land (R_L), marine air mass retention ratio within the boundary layer (R_B), air mass exposure to chlorophyll a (AEC), and averaged meteorological parameters along trajectories including relative humidity, temperature, boundary layer height (harmonic mean) and wind speed (along trajectories over oceanic region only). The MATLAB code for calculating AEC is also given.
