Particle habit imaging using incoherent light : a first step toward a novel instrument for cloud microphysics
(2011-04)
The imaging unit of the novel cloud particle instrument Particle Habit Imaging and Polar Scattering (PHIPS) probe has been developed to image individual ice particles produced inside a large cloud chamber. The PHIPS produces ...
Exploring the surface roughness of small ice crystals by measuring high resolution angular scattering patterns.
(2011)
Surface roughness of atmospheric ice particles is an important yet poorly investigated microphysical property in the context of the climate impact of cirrus and mixed-phase clouds. Measurements of single particle two-dimensional ...
Retrieving the size of particles with rough surfaces from 2D scattering patterns
(2011)
Scattered intensity measurement is a commonly used method for determining the size of small particles. However, it requires calibration and is subject to errors due to changes in incident irradiance or detector sensitivity. ...
Light scattering by ice particles in the Earth's atmosphere and related laboratory measurements
(University of Helsinki, 2010)
The microphysical properties of ice crystals, such as size, shape, concavity and roughness, are important in the context of radiative properties of ice and mixed phase clouds. Limitations of current cloud probes to measure ...
