A total of 10 boundary layer sampling events over the Pacific Ocean were analyzed for the purpose of defining the sea-to-air CH₃I flux using a mass balance photochemical model. These events were recorded on the National Center for Atmospheric Research (NCAR) C -130 aircraft as part of the Aerosol Charac-terization Experiment (ACE 1). The latitude range, covered by these events, was 2˚N to 55˚S. The flux ranges were 4 to 33 nmol m^-2 day^-1, with an average value of 11±8 nmol m^-2 day^-1. This study also indicated that the current approach to estimate the flux was not systematically different from the sea-air exchange model.
