Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric aerosol and a detailed knowledge of the formation, properties and transformation of SOA is therefore require...
Process based inventory of isoprenoid emissions from European forests: model comparisons, current knowledge and uncertainties
isoprenoid emissions European forests model comparisons
2009/6/22
Large uncertainties exist in our knowledge of regional emissions of non-methane biogenic volatile organic compounds (BVOC). We address these uncertainties through a two-pronged approach by compiling a...
