As a first-year college student in Delhi, I often check the AQI because it directly affects daily life. Most of the time, the numbers are discouraging, with the city covered in a grey haze. Breathing clean air feels like a rare experience. But recently, after a spell of heavy rain, I noticed something different. The sky looked clearer, the air felt fresher, and the AQI apps showed a big drop in pollution levels. It made me curious, so I read about why this happens. Scientists call it “wet deposition,” where raindrops pull down dust and pollutants from the atmosphere. This natural clean-up shows how quickly conditions can change. Before the rain, AQI levels were in the “very poor” range, and within hours after, they moved closer to “moderate.” The difference was visible to everyone on the streets. You sent It made me wonder: if rain can do this in just one day, what would happen if we consistently controlled emissions and dust ourselves? Maybe clean skies wouldn’t feel like a once-in-a-while gift. As students, I think it’s important we observe these changes and spread awareness. Delhi deserves air that is safe every day, not only after a storm.
