Product overview
Visibility is a routine item of meteorological observation, an optical index reflecting the degree of atmospheric turbidity, an important physical quantity characterizing the degree of near-surface atmospheric transparency, and can be used to analyze the degree of air pollution under specific conditions. It has important influence on aviation, navigation, land transportation, target detection and identification, and military activities. In meteorology, visibility is one of the important parameters to identify the characteristics of air mass. It represents the atmospheric optical state at that time and is closely related to the change of weather. It has practical significance in weather forecasting and environmental monitoring.
The index of DNQ1 forward scattering visibility meter is based on the requirements of Functional Specification for Forward Scattering Visibility Meter formulated by the Comprehensive Observation Department of ZG Meteorological Bureau. In May 2011, Huayun Company used DNQ1 forward scattering visibility meter to participate in and pass the visibility meter assessment organized by meteorological detection Center. In the assessment process, DNQ1 performed stably. The effect is ideal.
