California-Native Trees Uptake of Acyl Peroxynitrate Keeps Nitrogen Oxides From Re-entering Atmosphere

Atmospheric Chemistry, Carbon Cycle, & Climate (AC4)-funded researchers determine acyl peroxynitrate, one possible result from nitrogen oxide (NOx) reacting in the atmosphere, can act as a NOx sink rather than a reservoir in rural and remote forested regions.
