On variation of visibility and air pollution in Meizhou Bay;

Lanzhou Aerosol Optical Depth in Winter and Their Relation with Visibility;

Analyses on Variation Trends of Atmospheric Visibility and Its Effect Factor in Muilt-Cities in Central Liaoning;

So using continuous spectrum sun-photometer and forward scatter visibility sensor, we measured the atmosphere column optical characteristic and plan extinction coefficient on earth on the base of two experiments, respectively.

The intensity of forward-scattered light is measured by the forward-scattering visibility sensor, which determines the extinction coefficient of the air, then the visibility can be obtained.

Low-visibility occurrence at Chengdu Shuangliu Airport covers almost one third of a year.

Among them, the influence of the low-visibility processes caused by fog, rainfall and other weathers on transportation have been special great.

Application research of visibility meter in laser-ranging ability test;

In order to improve the technology in atmosphere detection and explore new,faster,and more accurate methods to retrieve atmosphere visibility,the atmosphere visibility was simultaneously measured in Qingdao with a micro-pulsed lidar,designed by Ocean Remote Sensing Laboratory,Ocean University of China,and a NQ-1 commercial visibility meter respectively.

Automatic detection of airfield runways in forward-looking aerial images with low visibility;

Climatic characteristics of low visibility in Urumqi City in recent 30 years;

In this paper,the working principle,installation configuration and data collection of the monitoring equipments working under low expressway visibility conditions are introduced through analysis and research on the special climate conditions in southern China and with reference to the low visibility influence of the harsh climate conditions such as fogs,storms,ices,snows,etc.
