PM2.5



Enjoy your outdoor activities.

Ozone: Ozone is a gas composed of three atoms of oxygen (O3). Ground level ozone, or "bad" ozone, is created by chemical reactions between oxides of nitrogen (NOX) and volatile organic compounds (VOC).


ppb: Parts per billion - a unit of measure

PM2.5: Fine inhalable particulate matter (also called particle pollution) with diameters that are generally 2.5 micrometers and smaller.


μg/m3: Microgram per meter cubed - a unit of measure

About the Air

Quality Index (AQI)

About Pollution Levels at this Village Green Bench

This Village Green bench shows air quality two ways. The blue scale shows minute-by-minute pollution levels right at this bench. The blue scale tells you if pollution is low, medium or high.


The multi-colored scale shows current air quality as the Air Quality Index (AQI) for your general area. The AQI is based on data from official, highly-accurate, government monitors that measure over a larger area than the sensor at this bench. The AQI provides information about steps you can take to protect your health.

Welcome to the Village Green Project

a research effort to discover new ways of measuring air quality and weather conditions in community environments.



Measuring and communicating on-the-spot air quality and weather conditions for research and awareness

Developing small and rugged data collection systems that can be powered by the wind and sun

Partnering with communities to pilot test the new technology in outdoor community spaces.

About Village Green

The Village Green project is a community-based activity to demonstrate the capabilities of new real-time monitoring technology for residents and citizen scientists to learn about local air quality. The goal of the project is to provide the public and their communities with information previously not available about their local air quality and engage communities in air pollution awareness.
A pilot station in Durham, NC has demonstrated the air monitoring station's ability to monitor several common air pollutants in real-time and make the data available online and by smartphone. The Village Green Project is expanding to five other locations across the U.S. to evaluate the station's operation under different weather conditions and to increase awareness of the availability of this new community-based air pollution measurement system. Each station provides minute-to-minute air measurements for ozone, particulate matter, and weather data to the public online.
