Visibility Sensor FAQs
What is a Visibility Sensor?
Visibility sensor is an instrument that provides real-time visibility data output by means of instrument simulating human eyes.
What does Visibility mean weather?
What Is The Monitoring Distance of Visibility Sensor?
In fact, the monitoring distance is not the actual distance, but the ideal value calculated by the model.
It refers to the distance values that can be detected under the same meteorological conditions, especially in mountainous areas where the fog is obvious, and the measured values can not represent the actual visibility of the local area.
How does a Visibility Sensor work?
It’s the volume of air an automated weather station uses to calculate visibility. Visibility should be an easy concept. … The sensor system—which includes a transmitter, receiver, and processor—determines visibility. The transmitter sends out a cone of light twice per second.
What does good Visibility mean?
The distance at which a given standard object can be seen and identified with the unaided eye. the ability to give a relatively large range of unobstructed vision: a windshield with good visibility.
What is the instrument used to measure visibility?
A typical visibility sensor used at synoptic observing stations is shown below. It applies the forward scattering characteristics of light to measure the extinction coefficient of a beam generated by a high intensity xenon strobe transmitter directed at a volume of air close to the sensor.
