Atmospheric visibility sensor based on backscattering ...

· An new atmospheric visibility sensor is described which uses an empirical relationship between atmospheric visibility and lidar backscatter signals. Specifically, autocorrelation analysis is performed for lidar backscatter signals and the autocorrelation coefficients are shown to be a function of the correlation distance. The slope of this function is then connected to the atmospheric visibility …

Introduction to atmospheric visibility estimation

Introduction to atmospheric visibility estimation Alec Bennett, BIRAL March 2012 Visibility is usually referred to as the maximum horizontal distance through the atmosphere that objects can be seen by the unaided eye. Visibility will depend upon several factors, for example: The size and colour of the object to be observed against the sky in the horizon The brightness of the sky itself ...

the wider atmospheric conditions. Both types of visiometers are used at airports, where estimation of visibility is particularly important since it will determine the distance at which the runway (or its lights) is visible to the pilot on approach. As such, visibility is normally referred to as Runway Visual Range (RVR) by the aviation community. Another term used for
