In the myriad nature, visibility, as an important index to measure the transparency of the atmosphere, directly affects people's travel safety, air transportation and ecological environment monitoring. With the rapid development of science and technology, visibility meteorological monitoring station came into being, it is like a guardian with a discerning eye, through layers of fog, for us to reveal the true face of the atmosphere.

The WX-NJD10 visibility meteorological monitoring station mainly uses advanced instruments such as scatterometer and transmometer to calculate the visibility of the atmosphere by measuring the scattering or absorption characteristics of particles in the atmosphere. The scatterer transmits the laser beam and receives its scattering light intensity in the atmosphere, and calculates the real-time visibility value according to the relationship model between the scattering light intensity and visibility. The transmissometer reflects the transparency of the atmosphere by measuring the transmittance of light between the transmitting end and the receiving end, and then calculates the visibility.

Visibility The importance of meteorological monitoring stations

‌ ensure traffic safety ‌ : in fog, haze and other low visibility weather conditions, visibility meteorological monitoring stations can monitor and provide accurate visibility information in real time, provide decision-making support for traffic management departments, timely take speed limit, road closure and other measures to ensure road traffic safety.

‌ Support for air transport ‌ : Air transport has high visibility requirements. Visibility weather stations can provide real-time visibility data to airports to ensure that flights take off and land in safe weather conditions and avoid flight delays or cancellations due to low visibility.

‌ Help Environmental monitoring ‌ : Visibility is closely related to the concentration of particulate matter in the atmosphere. Through long-term monitoring of visibility data, it can indirectly reflect the change trend of atmospheric environmental quality, provide scientific basis for environmental protection departments, and formulate effective management measures.

In recent years, with the continuous development of technologies such as the Internet of Things and big data, visibility meteorological monitoring stations have also ushered in new development opportunities. By combining these advanced technologies with visibility monitoring, real-time transmission of monitoring data, intelligent analysis and early warning release can be achieved, further improving the accuracy and timeliness of monitoring.
