Visibility & present weather sensors

Visibility is an important parameter within aviation, harbour and road monitoring applications. In the past this was a parameter which was manually observed and broadcasted to users.

Although this method is still applied, many Automatic Weather Station (AWS) are provided with a visibility (and present weather) sensor. Forward and backward scatter principles are quite common, while transmisiometers are often used for airfield applications. Many aviation authorities nowadays also accept the use of forward scattering sensors. Observator has chosen the use of the Biral-range for these kinds of measurement. Their visibility sensor has proven to be accurate and long lasting within marine environments while present weather can also be determined using their range.
