Abschätzung biogener Kohlenwasserstoff-Emissionen. Beitrag biogener Emissionen zum Sommersmog

A procedure for the estimation of hydrocarbon emissions caused by deciduos forests, coniferous forests, mixed forests, agricultural areas and grassland is described. Here, the hydrocarbons are divided into three groups: isoprene, monoterpenes and other biogenic-emitted, volatile organic compounds. The emissions are calculated for a summer day in the eastern part of Germany using a land use data base. The spatial distribution of the emissions is represented as well as the variation of the emissions in the course of the summer day. The estimation of the emissions reveals that the daily amount of biogenic hydrocarbon emissions during the summer can have the same magnitude as the anthroplbgenic hydrocarbon emissions.
