This research aimed to present results about the mixing ratio and flux of monoterpenes at a forest region of the Brazilian Amazon. It was used micrometeorology instrumentation (using a Sonic Anemometer) and analytical chemistry by a Proton Transfer Reaction - Time of Flight - Mass Spectrometer, PTR-ToF-MS. The calibration of the spectrometer was performed regularly using a gravimetric mix of standard gas containing different masses of volatile organic compounds. The results showed average mixing ration of monoterpenes of 0.185 ppbv and maximum emission flux of 1.495 mg m-2 h-1. It was concluded that this region presented a significant emission of monoterpenes in relation to another tropical forest in central Amazonia, evidencing the needing...
