Abstract: This report presents the results and methodology of an intense study of rainfall frequency relationships throughout the Midwest (Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri, Ohio, and Wisconsin). Global total air–sea flux depends primarily on global mean surface ocean DMS concentration, and the spatial distribution of DMS concentration and the magnitude of the gas exchange coefficient are of secondary importance.
