First total OH reactivity emission measurements from a Nordic wetland
Volatile organic compounds (VOCs) are ever-present compounds in the air we breathe. They are emitted by natural and anthropogenic sources and are modified by atmospheric oxidants. VOCs affect air quality and human health, form and grow aerosol particles, and can impact Earth's radiative balance...

Volatile organic compounds (VOCs) are ever-present compounds in the air we breathe. They are emitted by natural and anthropogenic sources and are modified by atmospheric oxidants. VOCs affect air quality and human health, form and grow aerosol particles, and can impact Earth's radiative balance.

Especially in remote forested environ- ments, missing or unaccounted for reactivity has been substantial, caused by either unmeas- ured primary emissions or secondary oxidation products. This study presents OH reactivity and VOC measurements over a Nordic, subarctic wetland in summer.
