Development of global air-sea gas transfer products

The air-sea exchange of gases through physical and biogeochemical exchange processes is of significant interest to climate change research, and international efforts to understand and quantify these exchanges are central to the Surface Ocean Lower Atmosphere Study (SOLAS). Among the projects within SOLAS, there is an active effort to develop resources sufficient to create global coverage of estimated transfer velocities of climatically important gases and particles. These data sets (air and sea gas concentrations, direct measurement of fluxes, environmental variables, etc) and products (gas transfer velocities, fluxes, etc) are developed in a variety of ways (satellite, in situ, parameterizations, models, etc), and there is a central facilitator / project integrator for this effort within SOLAS. In this presentation, we will provide the international framework for the research objectives for the development of global gas transfer velocities, provide descriptions of the developed products for various gases (DMS, CO2, etc), and discuss future areas of focus for the effort.
