    • Application of RTDF to particles with curved surfaces 

      Hesse, E.; McCall, D.; Ulanowski, Z.; Stopford, C.; Kaye, Paul H. (2009)
      The applicability of the ray tracing with diffraction on facets model is extended to particles with curved surfaces. This allows tests against T-matrix calculations for larger size parameters and modelling of light scattering ...

    • Application of RTDF to particles with curved surfaces 

      Hesse, E.; McCall, D.; Ulanowski, Z.; Stopford, C.; Kaye, Paul H. (University of Hertfordshire, 2008)
      The applicability of RTDF is extended to particles with curved surfaces. This allows tests against T-matrix calculations for larger size parameter and modeling of light scattering by more realistic particle shapes, such ...

    • Co-ordinated Airborne Studies in the Tropics (CAST) 

      Harris, N. R. P.; Carpenter, L. J.; Lee, J. D.; Vaughan, G.; Filus, M. T.; Jones, R. L.; OuYang, B.; Pyle, J. A.; Robinson, A. D.; Andrews, S. J.; Lewis, A. C.; Minaeian, J.; Vaughan, A.; Dorsey, J. R.; Gallagher, M. W.; Le Breton, M.; Newton, R.; Percival, C. J.; Ricketts, H. M. A.; Baugitte, S. J-B.; Nott, G. J.; Wellpott, A.; Ashfold, M. J.; Flemming, J.; Butler, R.; Palmer, P. I.; Kaye, P. H.; Stopford, C.; Chemel, C.; Boesch, H.; Humpage, N.; Vick, A.; MacKenzie, A. R.; Hyde, R.; Angelov, P.; Meneguz, E.; Manning, A. J. (2017-01-23)
      The main field activities of the CAST (Co-ordinated Airborne Studies in the Tropics) campaign took place in the West Pacific in January/February 2014. The field campaign was based in Guam (13.5°N, 144.8°E) using the UK ...

    • Ice Crystal Classification Using Two Dimensional Light Scattering Patterns 

      Stopford, C. (2010-08-23)
      An investigation is presented into methods of characterising cirrus ice crystals from in-situ light scattering data. A database of scattering patterns from modelled crystals was created using the Ray Tracing with Diffraction ...

    • Initial investigation into using Fourier spectra as a means of classifying ice crystal shapes 

      Stopford, C.; Ulanowski, Z.; Hesse, E.; Kaye, Paul H.; Hirst, E.; Schnaiter, M.; McCall, D. (University of Hertfordshire, 2008)
      Fast Fourier Transforms of azimuthal light scattering patterns are investigated as a method for classifying cirrus cloud ice crystals. Small Ice Detector Mk. 2 data is compared to modelled reference data of various aspect ...

    • Investigation into Single Scattering Properties of Airborne Saharan Dust Particles 

      McCall, D.; Ulanowski, Z.; Hesse, E.; Stopford, C.; Kandler, K.; Kaye, Paul H. (2008)
      The phase functions of single mineral dust particles levitated in an electrodynamic balance have been measured. Normalized phase functions and the asymmetry parameter could be determined because nearly the full range of ...

    • Measurement and modeling of light scattering by small particles. 

      Hesse, E.; Ulanowski, Z.; McCall, D.; Stopford, C.; Kaye, Paul H. (University of Bremen, 2008)
      At the University of Hertfordshire we measure and model light scattering by small particles, in particular by such relevant for climate research. The measurements comprise phase functions, linear polarization of single ...
