This dataset contains the raw droplet freezing assay data used in the publication: "An evaluation of the heat test for ice-nucleating ability of minerals and biological material" by Daily et al (2022) in Atmospheric Measurement Techniques (https://doi.org/10.5194/amt-15-1-2022)

The data is organised into .csv files which correspond to individual figures as indicated by the filename. Files with _ns at the end of the file name indicate data is droplet freezing temperature as a function of active site density ns(T) or nm(T) format while _ff indicates data is droplet freezing temperature as a function of fraction of droplets frozen and no suffix indicates data is droplet freezing temperatures only.

All temperature data is in degrees celsius (degC).
