The effect of rainfall on CO_2 absorption across the air-water interface was investigated through laboratory experiments in a turbulent open-channel flow. The mass transfer coefficient on the liquid side is well correlated by both the mean vertical momentum flux of rainfall, M, and the mean kinetic energy of rain droplets impinging on the unit area of the air-water interface, KEF. However, it was not concluded which of M and KEF is a better parameter for expressing the rainfall effects on the mass transfer. The mass transfer coefficient obtained in this study corresponds to that obtained in wind-driven turbulence with wind speed which ranged from 13 to 15m/s. This suggests that it is of great importance to consider the rainfall effect on the CO_2 exchange rate between the atmosphere and ocean in precisely estimating the global carbon cycle by a climate model.
