Angularly resolved elastic scattering from airborne particles - Potential for characterizing, classifying, and identifying individual aerosol particles
Kaye, Paul H.; Aptowicz, Kevin; Chang, Richard K.; Foot, Virginia; Videen, Gorden (Springer Nature, 2007)Analysing the light scattering properties of individual airborne particles has become a powerful tool by which they may be characterized, classified, and in some cases, identified. The approach offers a non-invasive, ... -
Bio-aerosol fluorescence - Detecting and characterising bio-aerosols via UV light-induced fluorescence spectroscopy
Pan, Yong-Le; Eversole, Jay D.; Kaye, Paul H.; Foot, Virginia; Pinnick, Ronald G.; Hill, Steven C.; Mayo, Michael W.; Bottiger, Jerold R.; Huston, Alan; Sivaprakasarn, Vasanthi; Chang, Richard K. (Springer Nature, 2007)All aspects of fluorescence from a single or a cluster of bio-aerosol particles are treated in this chapter. The following topics are covered: light sources to induce fluorescence, detectors to sense fluorescence, excitation ... -
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 ... -
Detection of Airborne Biological Particles in Indoor Air Using a Real-Time Advanced Morphological Parameter UV-LIF Spectrometer and Gradient Boosting Ensemble Decision Tree Classifiers
Crawford, Ian; Topping, David; Gallagher, M.W.; Forde, Elizabeth; Lloyd , J R; Foot, Virginia; Stopford, Chris; Kaye, Paul H. (2020-09-29)We present results from a study evaluating the utility of supervised machine learning to classify single particle ultraviolet laser-induced fluorescence (UV-LIF) signatures to investigate airborne primary biological aerosol ... -
Intercomparison of Multiple UV-LIF Spectrometers using the Aerosol Challenge Simulator
Forde, Elizabeth; Gallagher, Martin; Walker, Maurice; Foot, Virginia; Attwood, Alexis; Granger, Gary; Sarda-Esteve, Roland; Stanley, Warren; Kaye, Paul H.; Topping, David (2019-12-09)Measurements of primary biological aerosol particles (PBAPs) have been conducted worldwide using ultraviolet light-induced fluorescence (UV-LIF) spectrometers. However, how these instruments detect and respond to known ... -
Quantifying bioaerosol concentrations in dust clouds through online UV-LIF and mass spectrometry measurements at the Cape Verde Atmospheric Observatory
Morrison, Douglas; Crawford, Ian; Marsden , Nicholas; Flynn, Michael; Read, Katie; Neves, Luis; Foot, Virginia; Kaye, Paul H.; Stanley, Warren; Coe, Hugh; Topping, David; Gallagher, Martin W (2020-11-28)Observations of the long-range transport of biological particles in the tropics via dust vectors are now seen as fundamental to the understanding of many global atmosphere–ocean biogeochemical cycles, changes in air quality, ... -
Real Time Detection of Airborne Bioparticles in Antarctica
Crawford, Ian; Gallagher, Martin; Bower, Keith; Choularton, Thomas; Flynn, Michael; Ruske, Simon; Listowski, Constantino; Brough, Neil; Lachlan-Cope, Thomas; Fleming, Zoe; Foot, Virginia; Stanley, Warren (2017-12-01)We demonstrate for the first time, continuous real-time observations of airborne bio-fluorescent aerosols recorded at the British Antarctic Survey's Halley VI Research Station, located on the Brunt ice shelf close to the ...
