10. Calculation of PCB transport
HYPACT – off-line Lagrangian Transport Model
EMISSION SOURCES
SDM: Mass relies= 10-4 g/s; Flux=400 pg/m2/s
(0.5km x 0.5km x 1m)
CDF: Mass relies= 10-3 g/s; Flux=4000 pg/m2/s
NY: Mass relies= 10-3 g/s; Flux=20 pg/m2/s
(4km x 10km x 20m)
For October 2001 NY source has an altitude of 1 m

24. CONCLUSIONS
What we got so far:
Calculated driving hydrodynamic fields
Conducted transport experiments
Evaluated relative contribution of different sources and their magnitude
Accounted for turbulent mixing within the boundary layer
Compared with observations
What could be done in future:
Aerosol microphysics. Aerosol processing in cloud/fog droplets. Interactive emission calculations. Study effect of other sources in the area.
