Thank you for your interest in our air quality maps. This website has been dormant since May, 2019 when the firewood heating season ended. Thermal inversions and the resulting air quality issues are winter time phenomena, and we encourage you to resume monitoring our maps in the fall. Please see our Facebook page at Keene Clean Air.
This map of current air quality conditions in Keene,
NH is updated every ten minutes.
