Abstract:
The dataset herein shows median change in ice-nucleating particle concentration after heating for the data from Eastern North Atlantic (ENA). The changes in absolute ice-nucleating particle concentration and percentage for ∆T of 0.5 °C are shown. The uncertainties are ± 0.5 °C with ± 23.5% for temperature and ice-nucleating particle concentration. Note: The 100% ice-nucleating particle concentration loss is not displayed.
