Using a regional atmospheric model of the eastern United States--the Comprehensive Air Quality Model with extensions (CAMx)--they quantify the variable impact that a fixed quantity of NOx emitted from individual sources can have on the downwind concentration of surface O3, depending on temperature and local biogenic hydrocarbon

The presence of nC31 is an indication of terrestrial biogenic hydrocarbons

The new findings add to emerging evidence that plants emit substantial amounts of so-called biogenic hydrocarbons
. "The biogenics are probably more important than were recognized," says Roger Atkinson of the University of California, Riverside.
