The data file contains an excel sheet entailing the data that was used to produce the figures of the manuscript: "A view on recent ice-nucleating particle intercomparison studies: Why the uncertainty of the activation conditions matters", which will be submitted to the journal "Atmospheric Measurement Techniques".

As the heterogeneous nucleation of ice-nucleating particles (INPs) is highly sensitive to the activation conditions, small changes in the nucleation temperature may result in significantly different numbers of activated INPs. In the manuscript we investigate the effect of errors in the temperature measurement of INP counters on the reported INP concentration. Further, we compare the uncertainty resulting from the temperature error to differences observed in recent INP intercomparison studies.
