Meteorology

A type of optical particle probe that measures the forward scattering caused by each particle or ensemble of particles intercepting a laser beam. The scattering is converted to an equivalent size via ...

Optical rain gauge

Weather; Meteorology

A gauge that measures the scintillation in an optical beam produced by raindrops falling between a light source and an optical receiver. By measuring the energy in selected frequency bands of the ...

Optical pathlength

Weather; Meteorology

(Sometimes called optical path or optical length. ) The line integral of the refractive index (real part) along a ray connecting two points in an optically homogeneous medium. Because refractive ...

Optical path

Weather; Meteorology

1. Same as line of sight. 2. The integral of the volume extinction coefficient over the path travelled by monochromatic radiation.

Optical array probe

Weather; Meteorology

An optical particle probe that records the size and shape of the shadow of each particle that intercepts and attenuates the illumination by a laser beam. Of these, shadowing probes differentiate ...

Optical imaging probe

Weather; Meteorology

An optical particle probe that records the size and shape of the shadow of each particle that intercepts and attenuates the illumination by a laser beam. Of these, shadowing probes differentiate ...

Optical counter

Weather; Meteorology

Device for counting the concentration of particles in air that takes advantage of the light scattering caused by particles. Modern instruments use laser light sources and are able to give information ...
