This study explores for the first time, the applicability of the Danish
Operational Street Pollution Model (OSPM) in the city of Buenos Aires
where street canyons are very irregular. The model is applied in an
irregular and asymmetric street canyon of a five–lane avenue near a
street intersection. Urban background concentrations estimated by the
DAUMOD model are considered. Meteorological information registered at
the domestic airport located in the city is used in calculations. Three
months of hourly NOx, NO2
and CO estimated concentrations are compared with measurements inside
the street canyon. Statistical evaluation of model results shows that
OSPM performance is quite good.
