- 'INSEKT' folder contains data collected on 28.03.2018 using the Ice Nucleation Spectrometer of the Karlsruhe Insitute of Technology (INSEKT). The columns represent: ice nucleation temperature (°C); the concentration of ice nucleating particles per liter (INP/L); the negative error related to the INP concentrations; the positive error related to the INP concentration.

- 'uL-NIPI' folder contains data collected on 28.03.2018 using the microlitre Nucleation by Immersed Particle Instrument (µl-NIPI). The columns represent: ice nucleation temperature (°C); the concentration of ice nucleating particles per liter (INP/L); the negative error related to the INP concentrations; the positive error related to the INP concentration.

- 'chambers' folder contains data collected on 22.03.2018, 28.03.2018, 26.04.2018 and 28.04.2018 using three Continuous Flow Diffusion Chambers (CFDCs) and one expansion chamber:
	* Portable Ice Nucleation Chamber (PINC) from ETH Zurich
	* Portable Ice Nucleation Chamber II (PINCii) from INAR (Helsinki) and Gothenburg University
	* Spectrometer for Ice Nuclei (SPIN) from the University of Eastern Finland 
	* Portable Ice Nucleation Experiment (PINE) from the Karlsruhe Insitute of Technology and the University of Leeds
The columns represent: year, month, day, hours (UTC+2), minutes, seconds, the concentration of ice nucleating particles per liter (INP/L), the ice nucleation temperature (°C).
