Abstract

The emission of Biogenic Volatile Organic Compounds (BVOCs) is very important and can lead in tropospheric ozone formation when these compounds are combined with anthropogenic pollutants. The photochemical smog (increase of tropospheric ozone) is a serious problem of large cities and was first described in 1950s derived from vehicular emissions from internal combustion engines and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants. This research studies the BVOCs emissions from vegetation using a computational mathematical model MEGANv2.04. The most important biogenic VOCs are isoprene and monoterpenes that both (especially isoprene) have a light dependent emission character. Calculations were held for Mediterranean region, for Greece and for Crete. The region over Mediterranean has vegetation with warm climate and sunlight so the isoprene emissions were expected to be high. Both summer and winter seasons were examined using meteorological data (temperature and solar radiation) and landcover data (vegetation cover and plant functional types). The spatial resolution is 30x30Km and the results were compared with several environmental parameters in order to clarify the impact of those parameters on isoprene emission.
