In situ detection of biological particles in cloud ice-crystals
Kerri A. Pratt,Paul J. DeMott,Jeffrey R. French,Zhien Wang,Douglas L. Westphal,Andrew J. Heymsfield,Cynthia H. Twohy,Anthony J. Prenni,Kimberly A. Prather +8 more
TL;DR: In this paper, aircraft-aerosol time-of-flight spectroscopy measurements of ice residues indicate that biological particles trigger ice formation in high-altitude clouds, which is one of the largest remaining sources of uncertainty in climate change projections.

TL;DR: The MOSAiC program as mentioned in this paper was organized into four subgroups: atmospheric state, clouds and precipitation, gases and aerosols, and energy budgets, using a variety of approaches, and across multiple scales.
Mass spectrometry of atmospheric aerosols--recent developments and applications. Part II: On-line mass spectrometry techniques.
TL;DR: Real-time mass spectrometry has been shown recently to provide the ability to probe the chemical composition of ambient individual particles <30 nm in diameter to further the understanding of how particles are formed through nucleation in the atmosphere.

Photochemical production of molecular bromine in Arctic surface snowpacks
Kerri A. Pratt,K. D. Custard,Paul B. Shepson,Thomas A. Douglas,Denis Pöhler,S. General,Johannes Zielcke,William R. Simpson,Ulrich Platt,David J. Tanner,L. Gregory Huey,Mark S. Carlsen,Brian H. Stirm +12 more
TL;DR: In this paper, measurements on Alaskan snow and sea ice suggest that photochemical reactions in surface snow serve as a major source of reactive bromine to the overlying atmosphere, contributing to episodic ozone depletion.
Improvements to an Empirical Parameterization of Heterogeneous Ice Nucleation and Its Comparison with Observations
Vaughan T. J. Phillips,Paul J. DeMott,Constantin Andronache,Kerri A. Pratt,Kimberly A. Prather,R. Subramanian,Cynthia H. Twohy +6 more
TL;DR: In this paper, a framework for an empirical parameterization (EP) of heterogeneous nucleation of ice crystals by multiple species of aerosol material in clouds was proposed in a 2008 paper by the authors.
