Shiliguri's air quality reflects the flat West Bengal Teesta River Siliguri Corridor at 122 metres — the strategic Chicken's Neck corridor connecting northeastern India — with vehicle density, transport hub, and market corridor generating elevated PM2.5. The dry winter northeast monsoon concentrates emissions and the extraordinary trans-Himalayan transit traffic volume represents Siliguri's most distinctive air quality contributor throughout most of the year.
