In 2021, EPA's Office of Research and Development initiated the Wildfire Smoke Air Monitoring Response Technology (WSMART) Pilot, loaning air monitoring technologies to state, local, and tribal air organizations to support supplemental air monitoring in areas affected by wildfire smoke and with observational data coverage gaps. During 2023, this pilot technology loan program will continue to provide several technology types – including stationary air sensor systems and a compact vehicle add-on mobile monitoring system (VAMMS) – to state and local air agency monitoring staff and professional tribal air quality staff members upon request. The equipment is not available for general public use.
