China has rolled out a system known as "grid management" to monitor air pollution in the Beijing-Tianjin-Hebei region and the neighboring area, in a bid to carry out targeted pollution control, according to the Ministry of Ecology and Environment.

The system covers 28 cities in the Beijing-Tianjin-Hebei region and the neighboring area, and divides the area into 3 by 3 kilometer square blocks, totaling 36,793. By applying satellite remote sensing technology and other weather statistical analysis, the system selects 3,600 blocks with high PM2.5 concentration levels as the key areas to monitor. 

Beijing further separated these blocks into smaller ones, added another 1,500 micro stations and began using mobile monitoring devices, in a bid to better target and monitor air pollution.

Since the system piloted in Cangzhou city, Hebei province last year, environmental authorities have taken great efforts in monitoring heavy air pollution. During the pilot process, the authorities identified 6,325 polluting enterprises, and helped to reduce PM2.5 level in the pilot area by 38.3 percent. The percentage of reduction was higher than the average of 20 percent in Cangzhou, which demonstrated the effectiveness of the grid management system.

In order to rally the local residents to participate in the efforts to reduce pollution and improve air quality, the data collected by the grid system will be released to the public. The cities that fail to meet the requirements will receive warnings from the Ministry of Ecology and Environment.

According to reports, the system will next be implemented in other areas in China, including 11 cities in the Fenhe-Weihe plain and 41 cities in the Yangtze River Delta area.
