Analysis of the Observation Results for Preferentially Oriented Particles in High-Level Clouds According to the EARLINET Lidar Network and MODIS Data

Autor: Alexey Skorokhodov, Alexander Konoshonkin

Publikováno v: Atmosphere, Vol 14, Iss 6, p 1018 (2023)

This analysis presents the results of observation episodes for high-level clouds consisting of ice crystals with different orientations in space, using the EARLINET lidar network and MODIS data over Europe from 2015 to 2022. The technique used involv

Light-Scattering Properties for Aggregates of Atmospheric Ice Crystals within the Physical Optics Approximation

Autor: Dmitriy Timofeev, Natalia Kustova, Victor Shishko, Alexander Konoshonkin

Publikováno v: Atmosphere, Vol 14, Iss 6, p 933 (2023)

This paper presents the light-scattering matrices of atmospheric-aggregated hexagonal ice particles that appear in cirrus clouds. The aggregates consist of the same particles with different spatial orientations and numbers of these particles. Two typ

Depolarization Ratio for Randomly Oriented Ice Crystals of Cirrus Clouds

Autor: Natalia Kustova, Alexander Konoshonkin, Victor Shishko, Dmitry Timofeev, Ilya Tkachev, Zhenzhu Wang, Anatoli Borovoi

Publikováno v: Atmosphere, Vol 13, Iss 10, p 1551 (2022)

The depolarization ratio and backscattering cross sections have been calculated for shapes and size of ice crystals that are typical in cirrus clouds. The calculations are performed in the physical-optics approximation. It is shown that the depolariz

Coherent Backscattering by Large Ice Crystals of Irregular Shapes in Cirrus Clouds

Autor: Natalia Kustova, Alexander Konoshonkin, Victor Shishko, Dmitry Timofeev, Anatoli Borovoi, Zhenzhu Wang

Publikováno v: Atmosphere, Vol 13, Iss 8, p 1279 (2022)

All elements of the scattering matrix have been numerically studied for particles of irregular shapes whose size is much larger than incident wavelength. The calculations are performed in the physical optics approximation for a particle size of 20 μ

Scattering database of dust particles with realistic shapes

Autor: Alexandra Tsekeri, Josef Gasteiger, Alexander Konoshonkin, Natalia Kustova, Thanasis Georgiou, Vassilis Amiridis

We constructed a new scattering database that takes into account realistically-shaped dust particles and a size range that includes most of the coarse mode of desert dust. In particular, we have used the irregular shapes of Gasteiger et al. (2011), a

Lidar backscatter simulation for angular scanning of cirrus clouds with quasi-horizontally oriented ice crystals

Autor: Natalia Kustova, Alexander Konoshonkin, Grigorii Kokhanenko, Zhenzhu Wang, Victor Shishko, Dmitriy Timofeev, Anatoli Borovoi

Publikováno v: Optics letters. 2022. Vol. 47, № 15. P. 3648-3651

Backscattering properties of ice crystals are numerically investigated in the case of plate-like quasi-horizontally oriented crystals of cirrus clouds. In this case, a vertically oriented lidar detects the specular reflection from the clouds while a
