Potential Implications of the Sesquiterpene Presence over the Remote Marine Boundary Layer in the Arctic Region

Atmosphere, 2023
We present reactive VOC observations over the North Pacific and the Arctic Ocean from airborne and shipborne measurements, investigating, in particular, distributions of biogenic volatile organic compounds that may be emitted from phytoplankton.
