چکیده
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 ratio, size and basal indentation.

Characterization of Small Ice Crystals Using Frequency Analysis of Azimuthal Scattering Patterns
Azimuthal scattering patterns obtained from ice crystals using the Small Ice Detector 2 are examined. They are converted to frequency spectra using Fast Fourier Transform. To classify the shape of the crystals, the spectra are compared to theoretical ones computed for a range of hexagonal crystal shapes, including hollow ones, of various aspect ratios.
متن کاملNOTES AND CORRESPONDENCE Characterization of Ice Crystals in Clouds by Simple Mathematical Expressions Based on Successive Modification of Simple Shapes
The technique based on the concept of successive modification of simple shapes using elementary mathematical functions to represent the shape and size of ice crystals in clouds is discussed. Two hypothetical samples of ice crystals, a single-habit sample of hexagonal plates and a multihabit crystal sample, are generated using a formula developed previously to illustrate the use of this techniqu...
متن کاملRemoval of Brilliant Green and Crystal violet from Mono- and Bi-component Aqueous Solutions Using NaOH-modified Walnut Shell
In the present work, the simultaneous determination of Brilliant green (BG) and Crystal violet (CV) dyes with overlapped absorption spectra in binary mixture solution, was carreid out using the partial least squares (PLS) and direct ortogonal signal correction-partial least squares (DOSC-PLS) methods. The results obtained indicate that by applying DOSC on the calibration and prediction data for...
متن کاملInvestigation on optical properties in the surface of KClxBr1-x mixed crystals irradiated to gamma radiation (A new approach)
Background: Similar to the thermoluminescence (TL) spectra, the optical parameters variations can also be used in TL crystals for dosimetry purposes. These optical parameters can include absorption, transmission and reflection coefficients. Materials and Methods: Single crystals of KBr and KCl which have been used in this research were grown from laboratory grade extra pure precursor p...
متن کاملCompton scattering as a probe for materials investigation
This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.
