Infrared Sensor to Predict Atmospheric Visibility and Rainfall Rate

Abstract

Abstract-The presented paper describes an instrument called Aurometer which was designed for both atmospheric visibility and rainfall rate measurement. The principle of operation of Aurometer is based on determining the amount of light scattered by particles in the air that passes through the sample volume. The achieved results show that simultaneous estimation of the atmospheric visibility and rainfall rate is possible.

Atmospheric visibility sensor based on backscattering using correlation coding method

“…5). Analyzing further, the contrast level of the dark object, located over the known distance R is estimated (Holejko et al 2013). Figure 5 depicts exemplary scenario, where the input parameters are: R = 1.2 km and k ≈ 0.18, thus the actual standard visibility is approximated on the level of V n ≈ 2.7 km.…”

New atmospheric visibility optical sensor based on correlation coding method

“…Scatterometers evaluate the light beam dispersion, however the reliability of such measurement outcome is of dubious nature [2][3][4]. Yet another branch of devices utilized for measurement of atmospheric visibility is based on the backscattering phenomenon [5][6][7]. In direct comparison to the forward scattering approach the operation of both solutions is presented in the Figure 1.…”
