The Ability of the Small Ice Detector (SID-2) to Characterize Cloud Particle and Aerosol Morphologies Obtained during Flights of the FAAM BAe-146 Research Aircraft
Cotton, R.; Osborne, S.; Ulanowski, Z.; Hirst, E.; Kaye, Paul H.; Greenaway, R. (2010)The Small Ice Detector mark 2 (SID-2), which was built by the University of Hertfordshire, has been operated by the Met Office on the Facility for Atmospheric Airborne Research (FAAM) BAe-146 aircraft during a large number ... -
Characterisation of atmospheric cloud particles using a light scattering probe
Hirst, E.; Kaye, Paul H.; Greenaway, R.; Field, P.R. (2000)When investigating the composition and dynamics of the atmosphere's particulate matter, particle shape is an important parameter by which classification and possibly identification of particles may be achieved. Spherical ... -
Discrimination of micrometre-sized ice and super-cooled droplets in mixed-phase cloud
Hirst, E.; Kaye, Paul H.; Greenaway, R.; Field, P.R.; Johnson, D.W. (2001)Preliminary experimental results are presented from an aircraft-mounted probe designed to provide in situ data on cloud particle shape, size, and number concentration. In particular, the probe has been designed to facilitate ... -
Light scattering from deformed droplets and droplets with inclusions 1 : experimental results
Secker, D.R.; Kaye, Paul H.; Greenaway, R.; Hirst, E.; Bartley, D.L.; Videen, G. (2000) -
Light scattering from deformed droplets and droplets with inclusions II : theoretical treatment
Videen, G.; Sun, W.; Fu, Q.; Secker, D.R.; Greenaway, R.; Kaye, Paul H.; Hirst, E.; Bartley, D.L. (2000)We provide theoretical results from the scattering of light by deformed liquid droplets and droplets with inclusions. With improved instrumentation and computer technologies available, researchers are able to employ ... -
A light scattering instrument for investigating cloud ice microcrystal morphology
Kaye, Paul H.; Hirst, E.; Ulanowski, Z.; Hesse, E.; Greenaway, R.; DeMott, P. (2008)We describe an optical scattering instrument designed to assess the shapes and sizes of microscopic atmospheric cloud particles, especially the smallest ice crystals that can profoundly affect cloud processes and radiative ... -
Measurement of the charge of airborne 3-10 um spherical dielectric particles charged in an AC unipolar charger
Dalley, J.E.J.; Greenaway, R.; Ulanowski, Z.; Hesse, E.; Kaye, Paul H. (2005)The charges of airborne 3, 5 and 10 um spherical dielectric test particles passing through a novel AC unipolar charger have been measured individually. The measurements show the effectiveness of the charger and provide ... -
Microfluidics based microcytometer: interfacing microfluidics with macrofluidics
Tracey, M.C.; Johnston, I.D.; Greenaway, R.; Sutton, N.; Doetzel, W.A. (Springer Nature, 1998) -
A Novel Instrument for Studying the Flow Behaviour of Erythrocytes through Microchannels Simulating Human
Sutton, N.; Tracey, M.C.; Johnston, I.D.; Greenaway, R.; Rampling, M.W. (1997)A novel instrument has been developed to study the microrheology of erythrocytes as they flow through channels of dimensions similar to human blood capillaries. The channels are produced in silicon substrates using ... -
Single-Particle Raman Spectrometer (SPaRS) for the non-destructive physico-chemical characterisation of aerosols
Greenaway, R.; Dalley, J.E.J.; Ulanowski, Z.; Hesse, E.; Kaye, Paul H. (2004)This project seeks to develop a prototype systems for the analysis of single levitated micrometre-sized particles captured from an ambient aerosol. The systems is designed to use Raman scattering to establish chemical ... -

A test of cirrus ice crystal scattering phase functions
Field, P.R.; Baran, A.J.; Kaye, Paul H.; Hirst, E.; Greenaway, R. (2003)In-situ ice crystal scattering has been measured in cirrus cloud with the Small Ice Detector laser scattering probe. Using light scattered from single particles (maximum dimension ∼<100 μm) at 4–10° and 20–40° we have ...
