General guidance by AQI band. Sensitive groups should act one level earlier.
Live pollutant levels
Each pollutant's 24-hour concentration is converted to a CPCB sub-index; the city AQI is the highest of them (the dominant pollutant). Bars show the sub-index out of 500.

AQI categories (India scale)
| AQI | Category | Associated health impact |
|---|---|---|
| 0–50 | Good | Air quality is considered satisfactory and air pollution poses little or no risk. |
| 51–100 | Satisfactory | Acceptable air quality; minor breathing discomfort possible for unusually sensitive people. |
| 101–200 | Moderate | May cause breathing discomfort to people with lung disease such as asthma, and to children and older adults. |
| 201–300 | Poor | May cause breathing discomfort to most people on prolonged exposure. |
| 301–400 | Very Poor | May cause respiratory illness on prolonged exposure; effects more pronounced for people with lung and heart disease. |
| 401–500 | Severe | Affects healthy people and seriously impacts those with existing diseases; avoid outdoor activity. |

About air quality in Modinagar
This page tracks the Modinagar Air Quality Index using measurements from Central Pollution Control Board (CPCB) monitoring stations, published through the Government of India's open-data portal. The AQI is a single number from 0 to 500 that summarises how polluted the air is and what it means for health, based on the concentrations of key pollutants — fine particulate matter (PM2.5), coarse particulate matter (PM10), nitrogen dioxide (NO₂), ground-level ozone (O₃), carbon monoxide (CO) and sulphur dioxide (SO₂).
Air quality in Modinagar changes through the day and across seasons. Levels are typically worse in the early morning and late evening when cooler, calmer air traps pollutants near the ground, and across North India they rise sharply in winter (roughly October to February) when temperature inversions, crop-residue burning and festival activity combine. Summer and the monsoon usually bring cleaner air as rain washes out particulates and stronger winds disperse them. Checking the current reading before outdoor exercise, a school run or a commute helps you decide whether to adjust timing, wear a mask, or keep windows closed.
We only display a number when a recent station reading exists — if you see "data updating", it means we are waiting on a fresh value rather than showing an estimate.
