This paper presents the Semi-Empirical Urban Street (SEUS) model.
SEUS is a simple model to estimate air pollutant concentrations in street canyons.
The performance of SEUS is evaluated in a street canyon in the city of Buenos Aires.
Estimated and observed NOx and NO2 hourly concentrations show good agreement.
SEUS model has been reasonable accurate, in spite of its simplicity.
