Abstract

An REA System for Measurements of Terpene Fluxes Guest contribution C.S.

The emitted NMHC differ in both reactivity, atmospheric lifetimes and products and especially the biogenic compounds play an important role in the photochemical formation of ozone. However, large uncertainties exist in the emission inventor
