11. The importance of vertical distribution of emissions
Data provided by Sonja Vidic (Sept. 2002)
Study of the effective height of emissions from 7 power plants and 1 industrial plant in Zagreb (Croatia)
Physical height of plants: 60m, 150m, 200m
Meteorological conditions from ,
Study of plant emission dispersion in monthly basis (Brigg’s formula)
Parameterised to typical height of 150m in EMEP model, same annual variation for all countries – Need for actual data from Parties
EMEP model parametrisation : allocated percent of emissions to different mndel heigths
45m 130m 240m 390m 590m 850m Emission sector
