Ice Nucleating Particles (INP) remain one of the biggest sources of uncertainty when mechanistically predicting the properties of clouds and precipitation in meteorological and earth system models. This paper presents the results from some comprehensive in situ and remote sensing measurements of these aerosols at a mountaintop site in the Eastern Mediterranean, performing a highly detailed study of their sources and properties, including those of dust and bioaerosol. The results are then used to generate new parameterisations that can be applied in large-scale models, thus providing an observational basis for improving future predictions.

Short summary
Ice nucleating particle (INP) concentrations are required for correct predictions of clouds and precipitation in a changing climate, but they are poorly constrained in climate models. We unravel source contributions to INPs in the eastern Mediterranean and find that biological particles are important, regardless of their origin. The parameterizations developed exhibit superior performance and enable models to consider biological-particle effects on INPs.
