A global climatology of ice nucleating particles at cirrus conditions derived from model simulations with EMAC-MADE3

Abstract: Abstract. Atmospheric aerosols can act as ice nucleating particles (INPs) and thereby influence the formation and the microphysical properties of cirrus clouds resulting in distinct climate modifications. From laboratory experiments several types of aerosol particles have been identified as effective INPs at cirrus conditions. However, the global atmospheric distribution of INPs in the cirrus regime is still highly uncertain as in situ observations are scarce and limited in space and time. To study the influen… Show more

“…The model is able to distinguish between aviation soot and soot from other sources (Righi et al, 2021), however, we choose the same freezing properties for these two soot classes in this study due to the uncertain freezing properties of aviation BC. The model improvements regarding glassy organics and crystalline ammonium sulfate were described in detail by Beer et al (2022) and are briefly summarized here. Importantly, the particle phase state is tracked for glassy organics and crystalline ammonium sulfate, as only the respective glassy or crystalline phase facilitates ice nucleation.…”
