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 ... -
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, ... -
