Revitalizing Delhi's Air Quality: Rainfall Brings Relief as Government Explores Artificial Rain Solutions




In a significant turn of events, several areas in Delhi, Gurugram, Noida, and the National Capital Region (NCR) experienced a welcome respite with a bout of rainfall on the night between Thursday and Friday. The precipitation, ranging from light to moderate intensity, has led to a noticeable improvement in Delhi's air quality, which had been a cause for concern in recent days.

This development coincides with the Delhi government's active pursuit of innovative solutions to combat the persistent air pollution. Visuals from locations such as Kartavya Path, ITO, and the Delhi-Noida border showcased the positive impact of the rainfall, while monitoring stations reported a significant drop in the Air Quality Index (AQI), registering values below 100 in the morning, compared to the previous night's levels exceeding 400.

The Regional Weather Forecasting Centre (RWFC) has forecasted further relief, predicting intermittent light-intensity rainfall across Delhi and its neighboring areas, including prominent locations like Rajiv Chowk, ITO, India Gate, Akshardham, Safdarjung, RK Puram, and Lajpat Nagar throughout Friday morning. Additionally, areas such as Noida, Dadri, Greater Noida, Faridabad, Jind, and others are also expected to benefit from the ongoing showers.

Delhi's Environment Minister, Gopal Rai, recently engaged with a team from IIT-Kanpur to explore the possibility of implementing 'artificial rain' through cloud seeding as a strategic measure to tackle the city's air quality crisis. Following the meeting, Minister Rai announced that if weather conditions remain conducive, artificial rain could be initiated on November 20-21.

Moreover, the Delhi government has taken a proactive stance by assuming the entire cost of implementing artificial rain to address the hazardous air pollution levels. The Chief Secretary has been directed to present the government's stance before the Supreme Court on Friday, demonstrating a commitment to finding sustainable solutions to the long-standing issue.

The proposed artificial rain method involves cloud seeding, a weather modification technique that disperses substances like silver iodide, potassium iodide, and dry ice into the air to encourage condensation and precipitation. This technique has been successfully employed in various parts of the world facing water scarcity or drought conditions.

As the city anticipates potential relief from artificial rain, coupled with the positive impact of ongoing showers, these measures signify a collaborative effort to address the critical air quality concerns in Delhi and its adjoining regions.
