Description: Das Projekt "WiSSCy: Impact of Wind, Rain, and Surface Slicks on Air-Sea CO2 Transfer Velocity - Tank Experiments" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Zentrum für Meeres- und Klimaforschung, Institut für Meereskunde (IfM) durchgeführt. The goal is to improve the understanding of the parameterization of air-sea gas exchange with emphasis on CO2. This is being done using the linear wind-wave tank facility of the University of Hamburg. Using this facility, gas exchange coefficients are inferred by measuring gas transfer under a wide variety of parameters such as wind, mechanically generated waves, rain, and surface films. Our emphasis is on the physical processes involved in the air-sea gas exchange and its quantitative measurement. Experiments are conducted with freshwater and with salt water to test the influence of salinity on the gas exchange parameters. All experiments are being performed for evasion and invasion to investigate if rain-induced gas transfer is symmetrical or asymmetrical. While these experiments do not address in great detail the small-scale processes that are involved in the transfer, they allow to determine parameterizations of the gas exchange as a function of parameters of the atmospheric boundary layers as they are needed in climate models and for the analysis of satellite data.
