"Now that we have collected a couple of years of data, we are starting a new phase of our project, which is analyzing the data and drafting our first reports. Clarity is helping us put together two internal reports and two public reports. In terms of internal reports, the first one is purely technical and allows our team to be more efficient and proactive in the maintenance of our network. As an example, it allows us to have 95% of our sites with uptimes greater than 95%. The second internal report aims to support our public policy team to advocate and influence for taking actions for better and cleaner air in WA, Western Australia.”
“Putting the power of air quality monitoring from institutions into the hands of communities is a game changer – every citizen, at any moment, can monitor air quality at any location in the city. Every politician must know that making decisions that improve air quality are standards that will protect us ourselves. Cooperation between local and central government is needed to determine an Action Plan for improving air quality. By implementing such a project in the municipality of Strumica, we have taken the first step (and the most important) towards such cooperation."
"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."

“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. This air quality sensor network is unparalleled in its size and scope, demonstrating Los Angeles Unified’s commitment to providing the safest learning environment for our students.”
"We wanted a network that would get real-time data out to the public immediately and show air quality changes in real-time — which we had been unable to do with our network of reference-grade equipment alone."
