Abstract:In recent years, inland water bodies such as lakes and reservoirs have been recognized as hotspots for carbon emissions, with the diffusion and release of greenhouse gases like carbon dioxide (CO2) and methane (CH4) at the water-air interface being the most significant pathways for carbon emissions from these water bodies. Diffusion release refers to the mass transfer process of gases between gas and liquid phases, where the gas-liquid mass transfer coefficient is a key parameter for calculating the flux of greenhouse gas diffusion. Wind speed is generally considered the primary factor affecting the gas-liquid mass transfer coefficient in the surface waters of lakes and reservoirs. However, most current research on the impact of wind speed on the gas-liquid mass transfer coefficient of greenhouse gases is based on field observations of tracer gases, lacking mechanistic experimental studies that consider the characteristics of gas-liquid mass transfer. This results in uncertainties when quantitatively assessin
