Single freezing and triple melting of micrometre-scaled (NH4)2SO4/H2O droplets
Abstract
Atmospheric aerosol droplets containing NH4+ and SO42− ions are precursors of cirrus ice clouds. However, the low-temperature phase transformation of such droplets is not understood yet. Here we show for the first time that micrometre-scaled (NH4)2SO4/
