Chemical Processing of Terpene Emissions from Forests


EMSL Project ID
3684

Abstract

Evaluations of NMOC emission inventories developed for rural and urban areas (which contain large uncertainties) necessitate direct measurement of landscape-scale fluxes. The main objectives of this research are (1) to develop aircraft-based methodologies for measuring the rate of exchange of NMOCs with environmental surfaces and (2) to make observations of the vertical flux and concentration profiles of NMOCs and their oxidation products above urban and rural landscapes in order to evaluate chemical-transport models and emission inventories. The measurement approach uses a variety of eddy sampling techniques in concert with fast- and slow-response chemical and turbulence sensors to determine air-surface exchange rates. The PTR-MS is one of these fast response sensors. This experiment will use the PTR-MS aboard the Battelle G-1 aircraft in local surveys of forest emissions in flights based out of Pasco.
