Droplet Freezing Data for INP Measurements in Beijing during March 2022

This dataset contains the data for immersion-freezing ice-nucleating particle (INP) measurements in Beijing during 2022. It includes sample and experiment metadata, droplet-level freezing temperatures for aerosol samples, pure-water and empty-membrane control data, hourly lidar depolarization ratios, and example Python scripts for recalculating and visualizing daily INP spectra. The raw droplet freezing data can be used to derive cumulative INP concentrations in sampled air after dilution correction and concatenation of the 1x and 100x dilution experiments.
