Journal ArticleDOI
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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
Journal ArticleDOI
Flight-based chemical characterization of biomass burning aerosols within two prescribed burn smoke plumes
Kerri A. Pratt,Kerri A. Pratt,Kerri A. Pratt,Shane M. Murphy,Shane M. Murphy,R. Subramanian,Paul J. DeMott,Gregory L. Kok,Teresa Campos,D. C. Rogers,Anthony J. Prenni,Andrew J. Heymsfield,John H. Seinfeld,Kimberly A. Prather +13 more
TL;DR: For example, during the Ice in Clouds Experiment-Layer Clouds (ICE-L) in the fall of 2007, smoke plumes from two small Wyoming Bureau of Land Management prescribed burns were measured by on-line aerosol instrumentation aboard a C-130 aircraft, providing a detailed chemical characterization of the particles as mentioned in this paper.
Journal ArticleDOI
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.
