A New Ice Nucleation Active Site Parameterization for Desert Dust and Soot

Source: Journal of the Atmospheric Sciences:;2016:;Volume( 074 ):;issue: 003:;page 699

Author(s): Ullrich, Romy; Hoose, Corinna; Möhler, Ottmar; Niemand, Monika; Wagner, Robert; Höhler, Kristina; Hiranuma, Naruki; Saathoff, Harald; Leisner, Thomas

Publisher: American Meteorological Society

Abstract: ased on results of 11 yr of heterogeneous ice nucleation experiments at the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) chamber in Karlsruhe, Germany, a new empirical parameterization framework for heterogeneous ...

Particle Habit Imaging Using Incoherent Light: A First Step toward a Novel Instrument for Cloud Microphysics

Source: Journal of Atmospheric and Oceanic Technology:;2011:;volume( 028 ):;issue: 004:;page 493

Author(s): Schön, Roland; Schnaiter, Martin; Ulanowski, Zbigniew; Schmitt, Carl; Benz, Stefan; Möhler, Ottmar; Vogt, Steffen; Wagner, Robert; Schurath, Ulrich

Publisher: American Meteorological Society

Abstract: he imaging unit of the novel cloud particle instrument Particle Habit Imaging and Polar Scattering (PHIPS) probe has been developed to image individual ice particles produced inside a large cloud chamber. The PHIPS produces ...

A Particle-Surface-Area-Based Parameterization of Immersion Freezing on Desert Dust Particles

Source: Journal of the Atmospheric Sciences:;2012:;Volume( 069 ):;issue: 010:;page 3077

Author(s): Niemand, Monika; Möhler, Ottmar; Vogel, Bernhard; Vogel, Heike; Hoose, Corinna; Connolly, Paul; Klein, Holger; Bingemer, Heinz; DeMott, Paul; Skrotzki, Julian; Leisner, Thomas

Publisher: American Meteorological Society

Abstract: n climate and weather models, the quantitative description of aerosol and cloud processes relies on simplified assumptions. This contributes major uncertainties to the prediction of global and regional climate change. ...

Comparison of Modeled and Measured Ice Nucleating Particle Composition in a Cirrus Cloud

Source: Journal of the Atmospheric Sciences:;2019:;volume 076:;issue 004:;page 1015

Author(s): Ullrich, Romy; Hoose, Corinna; Cziczo, Daniel J.; Froyd, Karl D.; Schwarz, Joshua P.; Perring, Anne E.; Bui, Thaopaul V.; Schmitt, Carl G.; Vogel, Bernhard; Rieger, Daniel; Leisner, Thomas; Möhler, Ottmar

Publisher: American Meteorological Society

Abstract: AbstractThe contribution of heterogeneous ice nucleation to the formation of cirrus cloud ice crystals is still not well quantified. This results in large uncertainties when predicting cirrus radiative effects and their ...

Quasi-Spherical Ice in Convective Clouds

Source: Journal of the Atmospheric Sciences:;2016:;Volume( 073 ):;issue: 010:;page 3885

Author(s): Järvinen, Emma; Schnaiter, Martin; Mioche, Guillaume; Jourdan, Olivier; Shcherbakov, Valery N.; Costa, Anja; Afchine, Armin; Krämer, Martina; Heidelberg, Fabian; Jurkat, Tina; Voigt, Christiane; Schlager, Hans; Nichman, Leonid; Gallagher, Martin; Hirst, Edwin; Schmitt, Carl; Bansemer, Aaron; Heymsfield, Andy; Lawson, Paul; Tricoli, Ugo; Pfeilsticker, Klaus; Vochezer, Paul; Möhler, Ottmar; Leisner, Thomas

Publisher: American Meteorological Society

Abstract: omogeneous freezing of supercooled droplets occurs in convective systems in low and midlatitudes. This droplet-freezing process leads to the formation of a large amount of small ice particles, so-called frozen droplets, ...

Resurgence in Ice Nuclei Measurement Research

Source: Bulletin of the American Meteorological Society:;2011:;volume( 092 ):;issue: 012:;page 1623

Author(s): DeMott, Paul J.; Möhler, Ottmar; Stetzer, Olaf; Vali, Gabor; Levin, Zev; Petters, Markus D.; Murakami, Masataka; Leisner, Thomas; Bundke, Ulrich; Klein, Holger; Kanji, Zamin A.; Cotton, Richard; Jones, Hazel; Benz, Stefan; Brinkmann, Maren; Rzesanke, Daniel; Saathoff, Harald; Nicolet, Mathieu; Saito, Atsushi; Nillius, Bjorn; Bingemer, Heinz; Abbatt, Jonathan; Ardon, Karin; Ganor, Eli; Georgakopoulos, Dimitrios G.; Saunders, Clive

Publisher: American Meteorological Society

Abstract: ding cloud and precipitation responses to variations in atmospheric aerosols remains an important research topic for improving the prediction of climate. Knowledge is most uncertain, and the potential impact on climate is ...
