Visibility and Temperature Updates
The dense fog brought widespread disruptions, impacting both rail and air travel. According to the India Meteorological Department (IMD), Delhi recorded a minimum temperature of nine degrees Celsius, adding to the chilly and hazy conditions. Visibility levels were notably poor, with commuters experiencing challenges navigating the city’s roads and highways.
Impact on Train and Air Travel
Train Services
The heavy fog caused delays in rail traffic, with 20 trains heading to Delhi from various parts of the country running late. Passengers were advised to stay updated on train schedules as disruptions continued through the morning.
Flight Operations
At Delhi Airport, authorities issued an advisory to passengers, warning that flights not equipped with CAT III technology could face delays. Travelers were urged to contact their respective airlines for the latest updates on flight statuses.
Air Quality: A Gradual Improvement
While the AQI at 7 a.m. on December 25 remained in the ‘very poor’ category, it showed progress from earlier levels. On December 24, the AQI had dropped from ‘severe’ to 369 by 4 p.m., prompting the Commission for Air Quality Management (CAQM) to ease Stage IV restrictions under the Graded Response Action Plan (GRAP). However, measures under Stages I, II, and III remain in place to prevent further degradation of air quality.
Area-Wise AQI Data
- Anand Vihar: AQI at 366
- Alipur: AQI at 324
- Ashok Vihar: AQI at 373 Other key areas across the national capital also reported AQI levels in the ‘very poor’ category, highlighting the persistent challenge of pollution in the region.
Winter’s Role in Pollution Levels
As winter deepens, lower temperatures and reduced wind speeds are contributing to the accumulation of pollutants in the air. Authorities and environmental experts stress the importance of continued monitoring and public cooperation to mitigate pollution levels. Vulnerable groups, including children, the elderly, and individuals with pre-existing respiratory conditions, are particularly advised to take precautions.

Efforts to Combat Pollution
The CAQM’s decision to lift Stage IV measures follows signs of improvement in air quality, but challenges remain. Residents are urged to adhere to existing guidelines, including:
- Minimizing outdoor activities during peak pollution hours.
- Avoiding the use of personal vehicles when possible.
- Properly disposing of waste to prevent open burning.
These measures are critical to sustaining recent progress and ensuring a healthier environment for Delhi’s residents.
CPCB’s AQI Classification and Health Risks
The Central Pollution Control Board (CPCB) classifies AQI levels as follows:
- Good (0-50): Minimal impact on health.
- Satisfactory (51-100): Minor discomfort to sensitive groups.
- Moderate (101-200): Breathing discomfort to vulnerable individuals.
- Poor (201-300): Breathing discomfort to most people on prolonged exposure.
- Very Poor (301-400): Health risks for all, especially vulnerable groups.
- Severe (401-450): Serious health effects on prolonged exposure.
- Severe Plus (450+): Emergency-level health impacts.
With Delhi currently in the ‘very poor’ range, health experts recommend wearing masks, using air purifiers indoors, and staying informed on daily AQI updates to minimize exposure.
Weather Forecast and Future Outlook
Mixed weather conditions are expected in the coming days, with foggy mornings likely to persist. Meteorologists predict a gradual rise in daytime temperatures, which may help disperse pollutants. However, the need for sustained efforts to tackle pollution remains critical.
Public Cooperation: A Key to Success
Authorities emphasize that tackling Delhi’s air quality crisis requires collective action. Residents are encouraged to:
- Reduce waste generation and participate in local clean-up drives.
- Use public transportation or carpool to reduce vehicular emissions.
- Support tree plantation initiatives to improve green cover.
Delhi’s battle against pollution is far from over, but the recent improvements signal that concerted efforts can make a difference. As the city navigates the winter season, staying vigilant and proactive will be essential to ensuring healthier air for all.
