Modelling the effect of size on the aerial dispersal of microorganisms (2012, unknown): “have been detected much higher than this, with 33% of particles associated with ice crystals at almost 8 km above Wyoming being biological in origin (Pratt et al., 2009).”
Long-term features of cloud microbiology at the puy de Dôme (France) (2012, background): “In addition, microbial cells could take part in the formation of clouds and precipitations by serving as cloud condensation nuclei (CCN) and/or ice nuclei (IN), respectively (Christner et al., 2008; Möhler et al., 2008; Morris et al., 2008; Pratt et al., 2009).”
Biological residues define the ice nucleation properties of soil dust (2011, background): “Recent in situ detection of cloud ice crystal residues at high altitudes revealed that 60 % of the dust particles contained biological material, which may have led to increased ice-nucleation efficiency (Pratt et al., 2009).”
Biogeography in the air: fungal diversity over land and oceans (2011, background): “Fungal spores are ubiquitous in the Earth′s atmosphere, where they can act as cloud condensation and ice nuclei and may thus influence the hydrological cycle and climate (Bowers et al., 20 2009; Christner et al., 2008; Hamilton, 1998; Henderson-Begg et al., 2009; Pratt et al., 2009; Prenni et al., 2”
Ice structures, patterns, and processes: A view across the icefields (2012, methodology): “A recent airborne field study analyzed submicrometer icenucleating aerosol particles at an altitude of up to 8 km using aerosol mass spectroscopy (Pratt et al., 2009).”
Suspendable macromolecules are responsible for ice nucleation activity of birch and conifer pollen (2012, background): “Biological particles comprised about a third of all ice crystal residues (Pratt et al., 2009) for an air mass sampled in the western United States.”
Improvements to an Empirical Parameterization of Heterogeneous Ice Nucleation and Its Comparison with Observations (2013, background): “…(Schwarz et al. 2006; Baumgardner et al. 2008) for black carbon con- centration; and d the aircraft aerosol time-of-flight mass spectrometer (A-ATOFMS) (Pratt et al. 2009b) for chemical composition of residues of cloud particles selected by a counterflow virtual impactor (CVI) (Noone et al. 1988).”
How important is biological ice nucleation in clouds on a global scale? (2010, background): “…for ice formation: Christner et al (2008) observed that ice nucleation active bacteria are ubiquitous in precipitation on different continents; Pratt et al (2009) identified 33% of the ice crystal residual particles sampled in a wave cloud over Wyoming as biogenic; and Prenni et al (2009)…”
Aerosol Mixing State: Measurements, Modeling, and Impacts (2019, background): “…source characterization approaches are not limited to primary sources either and have been used to probe SOA (Middlebrook et al., 2003), amines (Pratt et al., 2009b), oxalic acid (Sullivan & Prather, 2007), oligomers (Denkenberger et al., 2007), organosulfates (Hatch et al., 2011a, 2011b),…”
A Classical-Theory-Based Parameterization of Heterogeneous Ice Nucleation by Mineral Dust, Soot, and Biological Particles in a Global Climate Model (2010, background): “Recently, Prenni et al. (2009b) and Pratt et al. (2009) observed high percentages of biological IN in the Amazon basin and in a wave cloud over North America, respectively.”
Bacterial abundance and viability in long-range transported dust (2012, background): “It was also estimated that biological substances associatedwith dustmight enhance the efficiency of dust on ice crystal formation (Pratt et al., 2009).”
Ice nucleation activity of bacteria isolated from cloud water (2013, background): “Observations indicated that about one third of the ice crystals sampled by aircraft at high altitude in a cloud event over Wyoming contained a solid residue with a biological signature (Pratt et al., 2009).”
Immersion freezing of ice nucleation active protein complexes (2012, background): “…showed that the majority of non-biological substances found in atmospheric ice crystal residues, i.e., natural mineral dust (e.g., Twohy and Poellot, 2005; Pratt et al., 2009; Kamphus et al., 2010), are only ice active at lower temperatures (e.g., Hoose and Möhler, 2012; Murray et al., 2012).”
The adsorption of fungal ice-nucleating proteins on mineral dusts: a terrestrial reservoir of atmospheric ice-nucleating particles (2016, background): “Pratt et al. (2009) demonstrated that in mixed-phase clouds above Wyoming, mineral dust particles were the dominant ice crystal residues sampled, while 60 % of these mineral dust particles were internally mixed with an observable amount of biogenic and/or humic-like substances.”
