Short summary

Atmospheric bacteria are thought to act as ice nuclei influencing the cloud formation. We used the aerosols captured in the snow cover on alpine mountain to investigate the sequential changes of ice-nucleation activities and bacterial communities at high elevation. The snow-cover samples exhibited high ice nucleation corresponding to the increase in natural and anthropogenic dust particles. Terrestrial bacteria (Bacilli) recorded in snow cover increased in relation to ice-nucleation activities.
