Ice\nnucleation by different types of soot particles is systematically\ninvestigated over the temperature range from 218 to 253 K\nrelevant for both mixed-phase (MPCs) and cirrus clouds. Soot types were selected to\nrepresent a range of physicochemical properties associated with combustion\nparticles. Their ice nucleation ability was determined as a function of\nparticle size using relative humidity (RH) scans in the Horizontal Ice\nNucleation Chamber (HINC). We complement our ice nucleation results by a\nsuite of particle characterization measurements, including determination of\nparticle surface area, fractal dimension, temperature-dependent mass loss (ML),\nwater vapor sorption and inferred porosity measurements. Independent of\nparticle size, all soot types reveal absence of ice nucleation below and at\nwater saturation in the MPC regime (T>235 K). In the cirrus\nregime (T≤235 K), soot types show different freezing behavior\ndepending on particle size and soot type, but the freezing is closely linked\nto the soot particle properties. Specifically, our results suggest that if\nsoot aggregates contain mesopores (pore diameters of 2–50 nm) and\nhave sufficiently low water–soot contact angles, they show ice nucleation\nactivity and can contribute to ice formation in the cirrus regime at RH well\nbelow homogeneous freezing of solution droplets. We attribute the observed\nice nucleation to a pore condensation and freezing (PCF) mechanism.\nNevertheless, soot particles without cavities of the right size and/or\ntoo-high contact angles nucleate ice only at or well above the RH required for\nhomogeneous freezing conditions of solution droplets. Thus, our results imply\nthat soot particles able to nucleate ice via PCF could impact the\nmicrophysical properties of ice clouds.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320148113920","@type":"Researcher","foaf:name":[{"@value":"Fabian Mahrt"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320148114049","@type":"Researcher","foaf:name":[{"@value":"Claudia Marcolli"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320148114051","@type":"Researcher","foaf:name":[{"@value":"Robert O.
