In 2015, the Chinese Academy of Sciences set up a joint air quality observation network composed of 40 stations (points) across the country, and a ground monitoring network composed of 16 international standard air quality observation stations in Beijing, Tianjin and Hebei.

As early as the beginning of 2014, Professor Huang Jianping of Lanzhou University led a scientific research team to develop China's first multi-band Raman-fluorescence lidar system. The system can not only be used to detect haze change data and early warning at different altitudes, but also can be used in satellite data correction, medical meteorological observation and other fields. It is an urgently needed technology in my country's global climate change, space environment monitoring and other fields. "The strength of the instrument industry determines the industrial level of a country." Qinghua Technology CEO said. In 2015, he and his team developed gas analysis instruments for atmospheric environmental monitoring such as haze, reducing the cost of instruments using laser absorption spectroscopy to 1/10 of the existing instruments, and the accuracy is more than 1000 times that of traditional instruments. It is hoped to improve people's living environment through low-cost and high-precision instruments.

How to forecast haze

The forecaster of the Environmental Meteorological Center asked the chief forecaster on duty of the Central Meteorological Station to check the forecast conclusion. The Environmental Quality Forecast and Early Warning Center of the China Environmental Monitoring Station said that the current method is numerical forecast combined with objective correction. Data are collected through meteorological observation stations and satellite remote sensing, and then the data are input into forecast systems (such as the developed numerical forecast system for fog, haze and air pollution meteorological conditions and the China haze numerical forecast system) to obtain the results, and the forecast conclusion is further revised after the research and judgment and consultation. After the "dust settles", the on-duty forecaster will issue relevant forecast products to the outside world.

However, due to the complexity of haze formation, it is affected by the change of pollution source at any time, and it also needs new remote sensing instruments with higher precision. Many cities in China have not yet possessed the numerical prediction ability of haze. It is hoped that the forecast mechanism will be improved as soon as possible to realize the haze forecast. Of course, more important is to reduce the haze weather, the real people also a free breathing sky.
