(cest2017_00691) Estimating the biogenic non-methane hydrocarbon emissions over Attica.

摘要

Biogenic emissions affect the urban air quality as they areozone and SOA precursors and should be taken intoaccount when applying photochemical pollution models.The present study presents an estimation of the magnitudeof Non-Methane Volatile Organic Compounds emissions(NMVOCs) emitted by vegetation over Attica. Themethodology is based on computation performed with theaid of a Geographic Information System (GIS) andtheoretical equations in order to develop anemissioninventory on a 6x6km2 spatial resolution and in a temporalresolution of 1hr covering the Greater Athens Area for oneyear period. For this purpose, a variety of input data wasused: improved satellite land-use data, land-use specificemission potentials, foliar biomass densities, temperatureand solar radiation data. Hourly, daily and annual isoprene,monoterpenes and other volatile organic compounds(OVOCs) were estimated. Results delineate an annualcycle with increasing values from March to April, whilemaximum emissions were observed from July to August,followed by a decrease from October to December.
