“…Like Gaussian dispersion models, street-network models require only few flow specifications, which can be either imported from an external flow simulation or obtained through suitable parametrisations. The only street-network models currently used operationally are the SIRANE [71,72] model and its unsteady version SIRANERISK [69], which both contain built-in flow parametrisations.…”

“…However, estimating background concentrations above streets with a Gaussian plume model inhibits a comprehensive atmospheric chemistry treatment, impacting the modeling of secondary pollutant concentrations, such as O 3 , and the secondary formation of NO 2 concentrations. Although SIRANE uses a stationary hypothesis for pollutant transport, a new version of SIRANE, named SIRANERISK (Soulhac et al, 2016), removes the steady-state hypothesis and simulates dispersion above street canyons using a Gaussian puff model. The Model of Urban Network of Intersecting Canyons and Highways (MUNICH), developed by Kim et al (2018), presents a similar box-model parameterization as SIRANE, but it does not employ a Gaussian model to determine background concentrations.…”

“…On one side they allow for an investigation of the phenomena that are responsible of the pollutant transfer, depending on the geometrical characteristics of the domain [ 9 , 20 22 ]. On the other, they provide data sets that can be subsequently used to evaluate the accuracy of the dispersion models in prediction time-averaged concentrations [ 23 25 ].…”
