Short summary

Stratospheric aerosol particles were collected within the arctic vortex in late winter. The chemical composition of refractory particles were analyzed by scanning electron microscopy. More than 750 refractory particles with diameters above 500 nm were found consisting of silicates, Fe- and Ca-rich particles and metal mixtures. The detection of refractory particles in the late winter polar stratosphere has strong implications for the formation of polar stratospheric clouds and ozone depletion.
