What the number means
From Good to Severe, at a glance
India's CPCB scale runs 0–500 across six bands. The color is only ever shorthand for what the air does to you — here's the plain-language version.
0250500
Satisfactory51–100
Fine for most people. Unusually sensitive groups may notice minor discomfort.
Moderate101–200
People with asthma or heart and lung conditions should ease off prolonged outdoor exertion.
Poor201–300
Breathing discomfort likely on prolonged exposure. Sensitive groups should limit time outdoors.
Very Poor301–400
Respiratory effects likely on prolonged exposure. Keep outdoor activity short.
Severe401–500
Affects healthy people too. Avoid outdoor exertion; sensitive groups should stay indoors.
How we read the air
From station to a single number
AQIRadar doesn't invent a score — it follows CPCB's official method, end to end. Here's the path every reading takes.
- 01
Stations measure the air
CPCB's national monitoring network samples six pollutants — PM2.5, PM10, NO₂, SO₂, CO and O₃ — hour by hour, at stations across India.
- 02
The worst pollutant sets the number
Each pollutant gets its own 0–500 sub-index. The highest one becomes the AQI, so the headline number always reflects your biggest exposure right now.
- 03
One number, one colour, one action
That value lands in a CPCB band — Good to Severe — each with a colour, a plain-language meaning, and what it means for your day outdoors.

The short version of how the number works and where it comes from.
Read the full methodology →India's official air quality index: a single 0–500 number across six bands, from Good to Severe. It distills the day's dominant pollutant into one colour and one plain-language description — the government's “one number, one colour, one description” idea.
CPCB calculates a separate sub-index for each pollutant and takes the worst one as the AQI, so the headline number always reflects your biggest risk. AQIRadar still shows every sub-index in the live panel, so nothing is hidden.
Same pollutants, different breakpoints and category names — so the same air can read as a different number. AQIRadar reports India's official CPCB scale rather than converting it, so what you see matches CPCB and government advisories.
At launch, hourly — drawn from CPCB's monitoring network via data.gov.in. The values shown on this pre-launch page are an illustrative sample so you can see how the product reads.
No. The notes follow CPCB's category guidance for the general population. For personal advice — especially with asthma, heart or lung conditions — talk to a clinician. The AQI is a guide, not a diagnosis.
