What is Mie code?

Solution techniques. Majority of existing codes for calculation of electromagnetic scattering by a single sphere is based on Mie theory which is an analytical solution of Maxwell’s equations in terms of infinite series.

What is meant by Mie scattering?

Mie scattering is elastic scattered light of particles that have a diameter similar to or larger than the wavelength of the incident light. The Mie signal is proportional to the square of the particle diameter. Mie scattering is often used to measure flow velocities applying Particle Image Velocimetry (PIV).

What are the examples of Mie scattering?

Mie scattering occurs when the diameters of atmospheric particulates are similar to or larger than the wavelengths of the scattered light. Dust, pollen, smoke and microscopic water droplets that form clouds are common causes of Mie scattering.

What is the difference between Rayleigh and Mie scattering?

Rayleigh line refers to the unshifted central peak observed in the spectroscopic analysis of scattered light. Mie scattering refers primarily to the elastic scattering of light from atomic and molecular particles whose diameter is larger than about the wavelength of the incident light.

Is Mie scattering selective?

When the solar beam encounters larger particles in the air, like cloud droplets or dust, all wavelengths are scattered equally. This kind of non-wavelength selective process, called Mie scattering, produces white-colored light, making clouds appear white, for example.

What is Mie scattering in remote sensing?

Mie scattering occurs when the particles are just about the same size as the wavelength of the radiation. Dust, pollen, smoke and water vapour are common causes of Mie scattering which tends to affect longer wavelengths than those affected by Rayleigh scattering.

Why are clouds white Mie scattering?

Another type of scattering (called Mie Scattering) is responsible for the white appearance of clouds. Mie scattering occurs when the wavelengths of visible light are more or less equally scattered. Clouds appear white when cloud droplets effectively scatter all wavelengths of visible light in all directions.

What is Rayleigh scattering example?

Rayleigh scattering of sunlight in Earth’s atmosphere causes diffuse sky radiation, which is the reason for the blue color of the daytime and twilight sky, as well as the yellowish to reddish hue of the low Sun.

How does Mie scattering affect the way the sky looks?

Mie scattering influences longer radiation wavelengths than Rayleigh scattering. The wavelength of Mie scattering is between to . Nonselective scattering: In visible wavelengths, water droplets and ice crystals scatter all wavelengths equally well so that the clouds in the sunlit sky looks white.

Is Mie scattering isotropic?

Mie scattering is the straightforward (if somewhat painful) application of Maxwell’s equations to an isotropic, homogeneous, dielectric sphere. It will be the first type of scattering examined as it is equally applicable to spheres of all sizes, refractive indices and for radiation at all wavelengths.
