Journal ArticleDOI
Overview of Ice Nucleating Particles
Zamin A. Kanji,Luis A. Ladino,Heike Wex,Yvonne Boose,Monika Burkert-Kohn,Daniel J. Cziczo,Martina Krämer +6 more
TL;DR: In this paper, new developments in identifying the heterogeneous freezing mechanisms, atmospheric relevance, uncertainties, and unknowns about ice nucleating particles (INPs) have been described, and the change in conventional wisdom regarding the requirements of INPs as new studies discover physical and chemical properties of these particles is explained.
Journal ArticleDOI
Efficiency of the deposition mode ice nucleation on mineral dust particles
Ottmar Möhler,Paul R. Field,Paul R. Field,Paul Connolly,Stefan Benz,Harald Saathoff,Martin Schnaiter,Richard H. Wagner,Richard Cotton,Martina Krämer,A. Mangold,A. Mangold,Andrew J. Heymsfield +12 more
TL;DR: In this paper, the deposition mode ice nucleation efficiency of various dust aerosols was investigated at cirrus cloud temperatures between 196 and 223 K using the aerosol and cloud chamber facility AIDA (Aerosol Interaction and Dynamics in the Atmosphere).
Journal ArticleDOI
Ice supersaturations and cirrus cloud crystal numbers
Martina Krämer,Cornelius Schiller,Armin Afchine,R. Bauer,Iulia Gensch,A. Mangold,A. Mangold,S. Schlicht,Nicole Spelten,N. Sitnikov,Stephan Borrmann,M. de Reus,Peter Spichtinger +12 more
TL;DR: In this article, the relative humidity over ice (RHice) of up to and more than 200% have been reported from aircraft and balloon measurements in recent years, from these observations a lively discussion continues on whether there is a lack of understanding of ice cloud microphysics or whether the water measurements are tainted with large uncertainties or flaws.
Journal ArticleDOI
Effect of sulfuric acid coating on heterogeneous ice nucleation by soot aerosol particles
Ottmar Möhler,S. Büttner,C. Linke,Martin Schnaiter,Harald Saathoff,Olaf Stetzer,Richard H. Wagner,Martina Krämer,A. Mangold,Volker Ebert,Ulrich Schurath +10 more
TL;DR: In this article, the effect of sulfuric acid coating on the ice nucleation efficiency of soot aerosol particles from a spark discharge generator was investigated in low-temperature aerosol and cloud chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere).
Journal ArticleDOI
Experimental investigation of homogeneous freezing of sulphuric acid particles in the aerosol chamber AIDA
Ottmar Möhler,Olaf Stetzer,S. Schaefers,C. Linke,Martin Schnaiter,R. Tiede,Harald Saathoff,Martina Krämer,A. Mangold,P. Budz,P. Zink,Jochen Schreiner,Konrad Mauersberger,W. Haag,Bernd Kärcher,Ulrich Schurath +15 more
TL;DR: In this article, the homogeneous freezing of supercooled H2SO4/H2O solution droplets was investigated in the aerosol chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere) of Forschungszentrum Karlsruhe.
