The files contain the data sets shown in the publication "Aerosol–cloud interactions: the representation of heterogeneous ice activation in cloud models" to appear in final form in the journal Atmos. Chem. Phys. in 2021. A preliminary discussion version of the manuscript is available under https://doi.org/10.5194/acp-21-1-2021. The files include a power point slide containing the schematic Fig.1 and xmgrace plot files containing the research data (ASCII) shown in Figs.2,3,4, and A1. Specifically (Gn means graph #n, Sm means set # m): in Fig.2, the black solid curve is listed under G0.S0; the blue solid curve G0.S1; dashed = G0.S2; dot-dashed = G0.S3 in Fig.3, curve (a) = G0.S0; black curve (b) = G1.S0, red curve (b) = G1.S1; black solid (c) = G2.S0 black dashed (c) = G2.S3; red solid (c) = G2.S1, red dashed (c) = G2.S2; curve (d) = G3.S0, black curve (e) = G4.S0; red curve (e) = G4.S1, black solid (f) = G5.S0, black dashed (f) = G5.S4, red solid (f) = G5.S1, red dashed (f) = G5.S2 in Fig.4, solid orange curve (a) = G0.S0, dashed orange (a) = G0.S1, solid red (a) G0.S2, dashed red (a) = G0.S3, solid blue (a) = G0.S4, dashed blue (a) = G0.S5; solid curve (b) = G1.S0, dashed (b) = G1.S1 in Fig.A1, solid black curve = G0.S0, solid blue = G0.S1
