Natural Sources SNAP11: NatAir NMVOC from natural and seminatural vegetation:
Improved compound specific emission model including description of canopy processes, saisonal change of LAI and improved leaf saisonal change of LAI and improved leaf biomass factorsbiomass factors, updated plant and chemical compound specific emission factors as well as default emission factors for general land use classes based e.g. on a potential vegetation map, improved and extended tree species data baseimproved and extended tree species data base, not only forests, but also agricultural and other land use included.
NO emissions from forests and agricultural soils:Improved emission modelnew soil and land management data base
Lightning (NO):Relations between lightning occurrence and meteorological parameters,updated emission factors
