Over 90 percent of the world’s population breathes polluted air.
Air quality monitoring is one of the foundational steps to ensuring a clean air for all. Measuring air pollution helps us…
Identify sources of pollution
Estimate the harms of pollution and benefits of clean air
Pressure decision-makers to act
Monitor and enforce existing air quality management policies
World Health Organization’s health-based guidelines for particulate matter (PM) are:
How does your air quality measure up to international guidelines?
Explore the data resources below to see if your country or city has publicly available data on air quality.
Outdoor Air Pollution
These sources have data on the levels of particulate matter (PM) in outdoor (ambient) air.
Provides near real-time data on particulate matter levels collected by U.S. embassies and consulates around the world.
Provides a collection of government-level and research-grade air quality data from monitors around the world.
Provides an updated map of annual mean outdoor PM2.5 level measurements.
Provides data on global exposure and concentration levels for countries and cities.
Provides data on outdoor area quality for 3,000 cities in 103 countries.
A global “Surfaced Particulate Matter Network” that combines ground monitoring and satellite modeling to estimate air quality around the world.
Provides air quality data and information for Indian cities involved in the Air Pollution Knowledge Assessment city program.
Household Air Pollution
Air pollution that is generated indoors contribute substantially to the health burden caused by air pollution. Household air pollution comes from combustion of dirty solid fuels such as wood, coal, kerosene and charcoal for household needs such as cooking, heating and lighting. Use these sources to get additional information on solid fuel use patterns in different nations:
Provides data on household solid fuel use and use of clean technologies for world populations.
