METEOROLOGY – AIR QUALITY & ATMOPHERIC CHEMITRY CALCULATOR
No2 Aqi
A precise tool.
What is the No2 Aqi & How does it work?
Nitrogen dioxide (NO₂) is a significant air pollutant that can have adverse effects on human health and the environment. It contributes to the formation of ground-level ozone and particulate matter, which are major components of smog.
The Air Quality Index (AQI) is a tool for reporting daily air quality. It indicates how clean or polluted the air is on a scale from 0 to 500. An AQI value of 50 or below represents good air quality, while higher values indicate poorer air quality.

Frequently Asked Questions
What is Nitrogen Dioxide (NO₂)?
Nitrogen dioxide is a harmful air pollutant that can cause respiratory issues and contribute to smog formation.
How does the AQI for NO₂ affect human health?
Higher AQI values indicate poorer air quality, which can lead to increased health risks such as asthma attacks and lung irritation.
What is the formula used to calculate the AQI for NO₂?
The AQI for NO₂ is calculated based on its concentration in parts per billion (ppb) using specific breakpoints set by environmental agencies.
Can I use this calculator for other pollutants besides NO₂?
This calculator is specifically designed for Nitrogen Dioxide. For other pollutants, you would need a different calculator or formula.
What does an AQI value of 50 indicate?
An AQI value of 50 indicates good air quality, meaning the air is clean and safe for most people.
How can I reduce NO₂ levels in my area?
Reducing NO₂ levels involves controlling emissions from vehicles, industries, and other sources that release nitrogen oxides into the atmosphere.
What are the health impacts of prolonged exposure to high NO₂ levels?
Prolonged exposure to high NO₂ levels can lead to serious respiratory problems, increased hospital admissions, and long-term lung damage.
