Apparatus and Method for the Analysis of Particle Characteristics using Monotonically Scattered light.
Particle Instruments and diagnostics; Kaye, Paul; Hirst, Edwin (1995-11-28) -
Biogenic cloud nuclei in the central Amazon during the transition from wet to dry season
Whitehead, James D.; Darbyshire, Eoghan; Brito, Joel; Barbosa, Henrique M.J.; Crawford, I.A.; Stern, Rafael; Gallagher, Martin W.; Kaye, Paul; Allan, James D.; Coe, H.; Artaxo, Paulo; McFiggans, G. B. (2016-08-03)The Amazon basin is a vast continental area in which atmospheric composition is relatively unaffected by anthropogenic aerosol particles. Understanding the proper- ties of the natural biogenic aerosol particles over the ... -
Characterisation and source identification of biofluorescent aerosol emissions over winter and summer periods in the United Kingdom
Forde, Elizabeth; Gallagher, Martin W.; Foot, Virginia; Sada-Esteve, Roland; Crawford, I.A.; Kaye, Paul; Stanley, Warren; Topping, David (2019-02-08)Primary biological aerosol particles (PBAPs) are an abundant subset of atmospheric aerosol particles which comprise viruses, bacteria, fungal spores, pollen, and fragments such as plant and animal debris. The abundance and ... -
Characterizing ice particles using two-dimensional reflections of a lidar beam
Goerke, Marissa; Ulanowski, Zbigniew; Ritter, Georg; Hesse, Evelyn; Neely, Ryan; Taylor, Laurence; Stillwell, Robert; Kaye, Paul (2017-07-01)We report a phenomenon manifesting itself as brief flashes of light on the snow surface near a lidar beam. The flashes are imaged and interpreted as specular reflection patterns from individual ice particles. Such patterns ... -
Cloud characterization using a particle-counter dropsonde
Ulanowski, Zbigniew; Kaye, Paul; Hirst, Edwin; Wieser, Andreas; Stanley, Warren (2015-04-12)Routine meteorological data is obtained in the atmosphere using disposable radiosondes, giving temperature, pressure, humidity and wind speed. Additional measurements are obtained from dropsondes, released from research ... -
Evaluation of machine learning algorithms for classification of primary biological aerosol using a new UV-LIF spectrometer
Ruske, Simon; Topping, D. O.; Foot, V.E.; Kaye, Paul; Stanley, Warren; Crawford, I.P.; Morse, Andrew; Gallagher, Martin W. (2017-03-03)Characterisation of bioaerosols has important implications within environment and public health sectors. Recent developments in ultraviolet light-induced fluorescence (UV-LIF) detectors such as the Wideband Integrated ... -

Ruske, Simon; Topping, D. O.; Foot, V.E.; Kaye, Paul; Stanley, Warren; Crawford, I.P.; Morse, Andrew; Gallagher, Martin W. (2016-07-13)Characterisation of bio-aerosols has important implications within Environment and Public Health sectors. Recent developments in Ultra-Violet Light Induced Fluorescence (UV-LIF) detectors such as the Wideband Integrated ... -
Observations of fluorescent aerosol-cloud interactions in the free troposphere at the High-Altitude Research Station Jungfraujoch
Crawford, I.P.; LLoyd, G; Herrmann, E; Hoyle, C.R.; Bower, K.N.; Connolly, Paul; Flynn, M.; Kaye, Paul; Choularton, T.W.; Gallagher, M. (2016-02-26)The fluorescent nature of aerosol at a high-altitude Alpine site was studied using a wide-band integrated bioaerosol (WIBS-4) single particle multi-channel ultraviolet - light-induced fluorescence (UV-LIF) spectrometer. ... -
A Universal Cloud and Aerosol Sounding System (UCASS) based on wide angle light scattering
Smith, Helen; Ulanowski, Zbigniew; Stanley, Warren; Kaye, Paul; Hirst, Edwin (2016-04-05)Summary This presentation discusses a new optical particle counter design, developed at the Centre for Atmospheric and Instrumentation Research, University of Hertfordshire. The Universal Cloud and Aerosol Sounding System ...
