Nocturnal vertical gradients in O 3 , PAN and PAA in a boreal forest: the role of chemical reactions, deposition and entrainment

Key Points

• This research aims to understand how atmospheric stability affects gradients of ozone, PAN, and PAA in boreal forests.
• Analysis of atmospheric conditions in boreal forest environments
• Measurement of O3, PAN, and PAA concentrations at various heights
• Assessment of chemical reactions and deposition processes
• High atmospheric stability corresponds with noticeable nocturnal gradients in O3, PAN, and PAA
• Entrainment from above the canopy reduces the concentration loss of these chemicals below the canopy
