Air quality in Assam today The AQI right now, city by city
Right now, Jorhat has the cleanest air of the 6 cities we track in Assam (AQI 66, Moderate), and Guwahati the worst (AQI 152, Unhealthy). Jorhat has the most tree cover, at 47.0% — #47 of 470 cities measured in India.
Every city is measured the same way, over the same 2 km around its center: the air quality right now, from ground stations where there are any, and its tree cover.

Lower is better on the US EPA index: 0–50 is Good, above 300 is Hazardous, and it reads differently from India's AQI (CPCB). Measured by Airleaf, refreshed hourly.

Air quality is the US AQI from ground monitoring stations via OpenAQ where available, otherwise the Open-Meteo / CAMS model, refreshed hourly. Tree cover is measured within 2 km of each city center from Sentinel-2 imagery; the rank compares every city measured in India.
Is this the same as India's AQI (CPCB)?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. India's Central Pollution Control Board (CPCB) publishes the National Air Quality Index on its own scale: 0–50 good, 51–100 satisfactory, 101–200 moderate, 201–300 poor, 301–400 very poor and 401–500 severe. The two scales don't line up. At moderate fine-particle levels the US scale reads higher: 55 µg/m³ of PM2.5 is 149 on the US AQI but about 92, "satisfactory", on India's. In heavy smog India's reads higher: 100 µg/m³ is 182 on the US AQI and about 232, "poor", on India's. CPCB also averages particles over 24 hours, so its figure moves more slowly than an hourly reading.

How much forest has Assam lost?
Since 2001, Assam has lost about 363,000 hectares of forest (about 3,600 km²): 13% of the forest it had in 2000. Most of it was lost to shifting farming, so much of it can grow back. About 127,000 hectares (35%) was deforestation: forest cleared for good for farms, mines or towns.
