Semester project or master thesis: Sources and properties of ice nucleating particles in southern Greenland

Ice nucelating particles (INP) are a subset of aerosols in the atmosphere that can form ice crystals at warmer temperatures than when droplets freeze homogeneously. They are typically low in abundance but have important implications for clouds and for weather and climate. The presence of ice crystals alters the optical properties and microphysical processes of clouds, affecting for example the probability of precipitation and cloud lifetime.

The aim of this project is to investigate the amount and properties of INPs from samples from southern Greenland, using an INP freezing assay (an offline method) and sample pre-treatments.
