| Abstract Scope |
Fugitive rooftop emissions are the largest single source of particulate pollution from primary aluminum production. Direct measurements of these emissions are expensive, time consuming, and provide only point-level information at the receptor. Air dispersion modelling can instead resolve the full spatial and temporal pattern of particulate concentrations. Hydro Sunndal, Europe’s largest primary aluminum smelter, is located deep in a valley at the end of Sunndalsfjorden, Norway. Sparse local weather measurements do not capture the complex local wind fields and atmospheric turbulence which drives dispersion. Publicly available prognostic meteorological data from the Norwegian Meteorological Institute were used to drive the Lagrangian dispersion model CALPUFF for PM10. Modelled concentrations agreed with measurements from a dedicated monitoring campaign to within 8.4% on average. This suggests that prognostic meteorology can reliably support dispersion assessments of fugitive emissions at complex sites. |
