| Popis: |
Light backscattering matrices are calculated within the physical optics approximation for hexagonal atmospheric ice particles distorted in different ways for the case of arbitrary spatial orientation and single scattering. A hexagonal prism with a height of 31.62 mu m and an external diameter of 22.14 mu m, which is typical for column-type particles observed in cirrus clouds, is chosen as a basic geometric shape. Three shape distortion methods for the particles are used: tilt, convexity and concavity; the angle of distortion varies from 0 degrees to 50 degrees for every particle type. The wavelength of incident radiation is 1.064 mu m. The calculation has shown a sharp decrease in the backscattering cross section with an increase in the angle of distortion for all particle types under study. |
