%X The flux of nitric oxide radical (NO£¿) during the daytime at the Seto Inland Seaatmosphere boundary was measured during the sea cruises embarked upon in September, 2013 and June, 2014. Atmospheric concentration of NO£¿ over the Seto Inland Sea and that present in the sea surface were measured. Results showed that average atmospheric NO£¿ concentrations measured over the Inland Sea in 2013 and 2014 were 4.4 ¡Á 10-10 and 5.2 ¡Á 10-10 atm, respectively. Also during the cruises, average wind speed of 2.0 and 3.2 m s-1 were measured in 2013 and 2014, respectively. In the surface seawater, the average NO£¿ concentrations measured were 2.1 ¡Á 10-11 and 1.9 ¡Á 10-11 mol NO£¿ L-1 in 2013 and 2014, respectively. Using appropriate formula, a daytime efflux of 0.22 pmol NO£¿ m-2 s-1 from the sea to the atmosphere was estimated for the two year-study. Assuming 8 h of solar intensity per day, about 1.54 ¡Á 106 g NO£¿ y-1 efflux from the 23,000 km2 Seto inland Sea surface was determined. The study confirmed that, during the day, sea could be an additional source of NO£¿ to the atmosphere
