Proven success with air quality monitoring

Adrian Rehn

Project Leader, Valley Vision

"Success doesn’t stop at measurement. We engaged in community-based planning with our community partners. We worked with neighbors to have intimate environmental justice listening sessions. We also had a self-guided EJ Tour where folks could walk around their neighborhood, looking at our data map, and then mark down things that they saw in the neighborhood that might be concerning. And we had a couple of fun virtual block parties, too!"

“We're a nonprofit, so we don't have a ton of capacity to mess around with tech. Clarity devices are easy to deploy and solar-powered, so you can put them in parks, on rooftops, wherever — and they just work. We can focus on working with our community members.”

“The Know Your Air Network provides us with vital air quality information that can be used to inform real-time decisions to protect the health and well-being of our school communities.

Superintendent/Principal, Pope Valley USD

“We chose Clarity because they provided up-to-date, local, scientifically-backed, and relevant data to make decisions about whether to keep students inside. Because of the geography and demographics in our county, the official air monitoring stations are about an hour away with hills in between, providing irrelevant data. We would have poor air quality and the official stations would be cleared; or the official stations would show heavy particulate levels and we would have clean air."

Matt Holmes

Air Quality Consultant and former Executive Director, Groundwork Richmond

"We couldn’t have done it with any other air quality monitoring solution. With their unique ability to operate off-grid, Clarity’s Node-S provided the ability to site our air quality monitors in the locations that mattered most to community members in Richmond. The data are reliable, real-time, and hyperlocal, and our network is now being used as a blueprint for AB 617, a landmark regulation that empowers communities to take control of air pollution."

Dr. Ian Longley

Principal Scientist - Air Quality, National Institute of Water and Atmospheric Research

"We needed high-density data to develop a model that was representative of a real situation on a very local scale – so multiple devices and multiple locations. The Clarity Node-S was ideal for this use case."
