Short summary

We experimentally determined gas-to-water equilibrium coefficients of difluoromethane, a refrigerant HFC-32, in aqueous salt solutions relevant to seawater at 3–39 °C to evaluate what portion of HFC-32 emitted into the atmosphere would be dissolved in the ocean． The portion in the ocean was estimated to be realistically limited to only about 1 % globally; however, in a lower-tropospheric semi-hemisphere (30 °S–90 °S), the portion was estimated to be at least 4 % in winter.
