Short summary
How ice particles form in polar mesospheric clouds is still a challenging question. We measured the water adsorption and onset conditions for ice growth on meteoric smoke analogue particles in the laboratory. We find that the particles activate by growth of amorphous ice and at much warmer conditions than previously assumed, affirming meteoric smoke as likely seeds in mesospheric ice clouds. We propose an ice-activation model and show that the particle charge does not play a significant role.
