Ice-nucleating ability measurements of quartz samples

This dataset contains ice-nucleating ability measurements of quartz samples using a Microlitre Nucleation by Immersed Particle Instrument (uL-NIPI). These measurements were taken as part of the Measuring atmospheric marine ice nucleating particles using technologies developed for cryopreservation project, funded by NERC (NE/M010473/1). The measurements where taken during the course of 2017 at the School of Earth and Environment, University of Leeds.

This dataset contains two files:
Quartz_Fraction_frozens_and_ns.csv: This file contains the freezing temperature, fraction frozen and active site density (ns) for 10 quartz samples. Each of these experiments were repeated a second time and are recorded as run 2.
Quartz_Time_series_ns.csv: This file contains the freezing temperatures and active site density (ns) for 3 quartz samples when left for differing periods of time in water and air.
