UN Prototype Air Sensor Unit Evaluated

In response to  a cooperative research and development agreement with the  United Nation’s Environmental Programme, EPA scientists conducted a 30-day performance evaluation of the UN’s prototype multipollutant air sensor pod. Data were collected and analyzed for the performance characteristics of the pod including its particulate matter sensor. The activity is part of ongoing research to evaluate and develop Next Generation air sensor technology. Results of the UN monitor study are described in the Performance Evaluation of the United Nations Environment Programe Air Quality Monitoring Unit Report. Other air sensor evaluations are available on the toolbox.

Announcing the Wildland Fire Sensors Challenge
EPA and five other federal agencies have announced a Wildland Fire Sensors Challenge seeking an accurate, lower-cost, and low-maintenance air quality monitoring system that can be used during a wildfire or controlled fire. The data provided by the sensor system will help federal, state, local and tribal agencies protect the health of first responders and communities affected by the smoke.

NACEPT 2016 Report: Environmental Protection Belongs to the Public, A Vision for Citizen Science at EPA

The National Advisory Council for Environmental Policy and Technology (NACEPT) formally transmitted its report to the EPA on citizen science. In this report, NACEPT developed thirteen robust recommendations regarding actions that EPA should take in response to technological and sociological developments in the area of citizen science. The report urges EPA to embrace citizen science and capacity building initiatives that further advance the agency's mission of protecting the environment and human health.

Results available for commercial air sensor evaluations

A study that evaluated the performance of 11 commercial air sensors has been published in the journal Atmospheric Measurement Techniques. Researchers compared the commercial devices with high-quality stationary EPA monitors to evaluate their ability to provide comparable data. They also evaluated the feasibility of deploying a local wireless sensor network. The sensors tested are listed in performance evaluation tables on the Air Sensor Toolbox web page.   

The paper is Community Air Sensor Network (CAIRSENSE) project: Evaluation of low-cost sensor performance in a suburban environment in the southeastern United States.

EPA Installing Air Monitoring Stations at Memphis Area Transit Facilities

EPA announces a collaborative project with the Shelby County Health Department (SCHD) and the Memphis Area Transit Authority (MATA) that is field testing newly installed, lower-cost air pollution sensor pods in the Memphis, Tennessee area.  Air sensor pods have been installed at sixteen locations including seven SCHD locations and three MATA transit facilities. 

EPA's CitySpace research project is field testing these air sensor monitors to understand how this emerging technology can add valuable information on air pollution patterns in neighborhoods. The sensors are being installed and data will be captured over a six month period concluding in February 2017.

Research projects to study how communities use air sensor technology 

Six research organizations have received funding from EPA’s Science to Achieve Results (STAR) program to develop and use low-cost air pollution sensor technology, while engaging communities to learn about their local air quality. 

The research teams will work with other organizations and community groups to explore how scientific data can be effectively gathered and used by communities to learn about local air quality and evaluate the accuracy of data produced by sensors and sensor networks. For example, one project will compare the sensors with high-quality data from existing monitoring technology that are used to support air quality regulations.
