AI may help Delhi children avoid morning pollution
In Delhi, winter brings very bad air quality because of something called temperature inversions.
This traps tiny pollution particles close to the ground, making the air unhealthy, especially in the morning.
Scientists looked at pollution data and found that pollution is much lower in the late afternoon.
They suggest that schools and sports teams should schedule outdoor activities for the late afternoon to keep children safe.
They also think that using AI can help predict the best times to go outside, making it easier for people to avoid the worst pollution.
Delhi's winter pollution levels are among the highest in the world due to temperature inversions.
Morning pollution levels are significantly higher than in the late afternoon.
Shifting outdoor activities to the late afternoon can reduce pollution exposure by up to 40%.
AI can help predict the best times for outdoor activities by analyzing various data sources.
Delhi's new winter pollution framework focuses on reducing emissions and using AI for better decision-making.
