Abstract:

The dataset herein shows the freezing assay-based ice-nucleating particle concentrations measured from samples collected onto 47 mm polycarbonate filters over approx. 4-day periods, along with ice-nucleating particle concentrations measured after heating the samples to 100 °C for 20 minutes. Data from the Eastern North Atlantic (ENA) site (2020) is shown. A summary of the freezing spectra of both untreated and heated samples from ENA is also provided.
