It is reported that the new radar green laser pointer technology is increasingly being adopted in the US coastal areas. The data will be used mainly to build the latest regional maps, which indicate where water is most likely to accumulate, where solar panels are most suitable for installation, and which communities are most in need of greening. The New York State Weather website has adopted a scanning laser Doppler wind measurement radar system. The radar system will be used in all weather stations across the state to provide real-time observation reports for the National Weather Service. Observation data will also be provided to the Department of Homeland Security and Emergency Affairs, allowing them to make better short-term forecasts and emergency management decisions. The agreement is planned by the University of Albany. The system captures wind speed, wind direction and aerosol concentration, as well as the boundary layer and cloud height distribution. These observations provide detailed 3D maps of the atmosphere with high spatial and temporal resolution.
Lidar technology refers to the inversion of atmospheric properties by detecting the radiation signals of lasers interacting with various molecules in the atmosphere and aerosols and other media, to quickly and widely monitor the atmospheric environment, and to carry out the evolution of urban pollution, the distribution of regional pollutants, Pollutant transmission and traceability. Dazhou is located in the mountainous area around the basin. In winter, atmospheric pollution sources have poor diffusion conditions. In addition, Dazhou’s existing five automatic monitoring stations for ambient air can only reflect the environmental quality of the monitoring points, and cannot fully reflect the current status of the atmospheric environment in the main urban area.
To this end, the Dazhou Environmental Protection Bureau cooperates with related enterprises to adopt green laser pointers radar technology to carry out three-dimensional monitoring of atmospheric pollutants in the main urban area. Through this technology, the environmental protection department can carry out voyage monitoring around the city, monitor the distribution of pollution from the ground to high altitudes along the line, and also carry out regional horizontal scanning monitoring. Through monitoring, the environmental protection department found 36 various sources of pollution, the main categories of which are industrial enterprises, construction sites, transportation sources (road dust, automobile exhaust), biomass burning, catering fumes, etc. In addition, the Dazhou Environmental Protection Bureau also found in the navigation monitoring that there is an air pollutant transport channel on the east and west sides of the main urban area.
