Abstract

Clouds containing ice are vital for precipitation formation and are important in determining the Earths radiative budget. However primary formation of ice in clouds is not fully understood. In the presence of ice nucleating particles (INPs), the phase change to ice is promoted, but identification and quantification of INPs in a natural environment remains challenging because of their low numbers. In this paper we quantify INP number concentrations in the free troposphere (FT) as measured at the High Altitude Research Station Jungfraujoch during the years 2014 to 2017. INPs were measured at conditions relevant for mixed-phase cloud formation at 241 to 242 K.
