*Figures according to Air Quality Warning and Decision Support System For Delhi under Indian Institute of Tropical Meteorology as of 6 am.

On Thursday, officials from the Delhi government said three mist spray drones will be hired to combat dust pollution in hotspot areas and gather real-time data on major pollutants, reported PTI. 

The drones will be deployed across 13 identified pollution hotspots to spray water and improve quality, they said. 

According to the officials, the exercise will help in settling dust particles, reducing particulate matter (PM) concentrations and mitigating the adverse effects of air pollution on public health and the environment. 

An environment department officer of the Delhi government said the process for hiring a vendor to operate the three drones has begun as a 15-day trial in hotspot areas. 

The drones will have a 17-litre tank and will be capable of covering one acre within 15 minutes. These drones will also integrate real-time air quality monitoring systems and high-resolution cameras for accurate data collection and reporting.  

The drones will work on pre-programmed routes to ensure comprehensive coverage for mist spray in most polluted areas as well as real-time monitoring. The air quality monitoring system, installed on the drones, will measure temperature, humidity, pressure, ozone, nitrous oxide, carbon monoxide, sulphur dioxide, PM10 and PM2.5 among other parameters.
