This study is to examine applicability of air-ion concentration to improve estimation accyracy of production rate of sea spray from the ocean. Concentration of air negative ions that is know to be influenced by generation of tiny sea spray was found to response to variation in production of film droplets induced by bubble bursting on water surface from our laboratory experiment. Also, concentration of air negative ions was observed in three ocean areas along Hokkaido, Japan; Sea of Japan, Sea of Okhotsk and the Pacific Ocean. The ion concentration was found to be correlated with the wind speed, wave height and whitecap ratio, all of which have been used as a model parameter of Sea Spray Generation Functions, indicating possibility of using air-ion concentration to accurate estimation of sea spray production.
