A comparison of methods for the assessment of odor impacts on air quality: Field inspection (VDI 3940) and the air dispersion model CALPUFF

► We compare methods to assess odor pollution from an anaerobic digestion plant for MSW. ► We applied the atmospheric dispersion model CALPUFF and the Odor Field Inspection. ► They were compared quantitatively and qualitatively over the same area for 6 months. ► The methods assessed similar spatial extents of nuisance in terms of odor frequency. ► The two methods provide complementary information about odor nuisance.
