Odor intensity was measured around two cattle feedlots to evaluate bet
ter their impact on surrounding residents. Odor measurements were. mad
e by multiple observers using a Scentometer. Observed odor intensities
were reproducible. Within a feedlot, odor intensities up to 120 DT we
re measured. Downwind 1 km or more values of 3 DT or less were typical
. Odor intensity measurements were useful as an objective description
of downwind conditions under a variety of climatic conditions.
