Workshop: Deliberating Performance Targets for Air Quality Sensors

Introduction

Over the past several years, miniaturized, lower-cost air monitoring sensors have entered the market and are now being used by researchers, industrial facilities, state and local government agencies, citizen scientists and the general public for a variety of purposes. Some of these new applications include:

• real-time high-resolution mapping of air quality at a far greater density than regulatory monitors;
• real-time public communication of sensor data;
• fenceline monitoring to detect emissions events;
• community monitoring to assess hot spots;
• personal monitoring; and
• applications to collect data in remote places.

Given the rapid adoption and technological advances of new air sensor technologies, there are numerous questions about how well they perform and how lower-cost technologies can be used for certain non-regulatory applications.

EPA is exploring the establishment of non-regulatory performance targets for air quality sensors to:

• know how well the technologies perform relative to specific performance targets;
• help distinguish the quality of different sensors for use in different applications;
• assist technology developers and improve end-user (consumer) confidence in the market; and
• inform third party conformity assessment organizations that may be interested in developing any future consensus-based standards or certification requirements for air sensor technologies.

Workshop Purpose

The Deliberating Performance Targets for Air Quality Sensors Workshop will solicit individual stakeholder views related to non-regulatory performance targets for sensors that measure fine particulate matter (PM2.5) and ozone in the United States. Through on-site and webinar discussions, national and international participants will address a range of technical issues involved in establishing performance targets for air sensor technologies. Discussion topics include:

• the state of technology with respect to sensor performance for various measures (e.g. limits of detection, linearity, interference, calibration, etc.);
• important attributes of sensor technology to include in a performance target and why;
• adoption of one set of performance targets for all non-regulatory purposes, versus a tiered approach for different sensor applications; and
• lessons learned from other countries about choices or trade-offs they’ve made or debated in establishing performance targets for measurement technologies.

Who should attend?

• People with technical expertise in measurement of ambient air pollution for a variety of purposes, to help identify issues and approaches to setting performance targets for air pollution sensors.
• People from state and local governments, industry, and the public interested in using air sensors for a range of applications.

Workshop Follow-up

A group of technical experts will work with EPA to document and summarize the individual perspectives communicated at the workshop, within the context of relevant scientific literature. This review of technical issues will be published in a science/engineering journal or report.
