FINC is a Drop Freezing Ice Nuclei Counter. This instrument was designed and built by NBD Group Members! It is used to cool and freeze micro droplets of water, and capture when the ice nucleates using a high speed camera. This allows us to to see if ice that contains different types of nanoparticles nucleates at a different temperature than pure water, and compare results with other nanoparticles found in the atmosphere. In the big picture, research using FINC can help to predict different kinds of cloud formation based on pollutants in the atmosphere.
