Short summary
Asian mineral dust is a crucial contributor to global ice-nucleating particles (INPs), while its size-resolved information on freezing activity is extremely rare. Here we conducted the first known INP measurements of size-resolved airborne East Asian dust particles. An explicit size dependence of both INP concentration and surface ice-active-site density was observed. The new parameterizations can be widely applied in models to better characterize and predict ice nucleation activities of dust.
