The national capital of India, Delhi, and its neighboring regions experienced a thick blanket of smog on a recent morning, significantly deteriorating the air quality to a 'Severe' level. This dense smog, which descended upon the region in the early hours, led to a sharp drop in visibility, impacting flight operations at the Indira Gandhi International Airport. The Air Quality Index (AQI) crossed the 400 mark, indicating hazardous levels of pollutants in the air, prompting concerns for public health.
The Commission for Air Quality Management (CAQM), the regulatory body responsible for overseeing air quality in the region, attributed the early-morning smog to an 'episodic event'. This suggests that the dense fog was a temporary phenomenon, possibly caused by a combination of factors such as stagnant air conditions, unfavorable wind patterns, and localized emissions. While the CAQM's statement indicates that the smog may dissipate, it underscores the persistent challenge of air pollution in Delhi, particularly during the winter months.
The dense smog resulted in zero-meter visibility at the Indira Gandhi International Airport at 8:30 am. The India Meteorological Department (IMD) reported that the Runway Visual Range (RVR) fluctuated between 125 and 500 meters at various locations. This reduced visibility significantly hampered flight operations, leading to delays and cancellations. The incident highlights the real-world impact of air pollution on critical infrastructure and public services, underscoring the need for robust measures to mitigate air pollution and protect public health.
