Northeast China usually sees a surge in the number of smoggy days in winter as a large amount of coal is burned to heat the region. According to reports, two UAS would be used to provide real-time inspection of the source of pollutants.
While one drone will record the real-time ground image and send it back immediately to the command centre, the other one will be flown over areas to inspect factories which might be polluting the air. The data collected will then be analysed and an air quality index of those areas at an altitude between 200 and 1,000 meters will be generated.
