MUNICH and SinG Modeling Training

Training Description

Street-in-Grid model (SinG) is a new multi-scale model of urban air pollution (Kim et al., 2018). SinG dynamically combines an Eulerian model (Polair3D) with a street-network model (MUNICH). This combined model aims at improving urban street-level pollutant concentrations by modeling both background and street-level concentrations at the same time. The model development has been conducted in Centre d’Enseignement et de Recherche en Environnement Atmosphérique (CEREA), joint laboratory of Ecole des Ponts ParisTech and EDF R& D by funding of EDF R& D and EDF R& D China. Its first application has been realized over the Paris region. This training covers topics including SinG concept, how to set up the configurations for a test simulation and how to generate input data.


  • Introduce the SinG model and its application over the Paris region (Kim et al., 2018)
  • Install SinG and run a test case of SinG
  • Prepare applications of SinG over a particular modeling domain of each participant

Training session: Street-scale modeling with MUNICH

The Model of Urban Network of Intersecting Canyons and Highways (MUNICH) allows the representation of the dispersion and physicochemical transformations of pollutants in streets. The street-segment volumes are discretized with an Eulerian approach. Breaking away from the Gaussian methodology, this approach allows one to model the transformations of pollutants (reactivity, gas/particle partitioning formation of ultrafine particles), as they are transported from the regional scale (background concentrations) to the street. The horizontal and vertical transport within the street and between the street and the background are parameterized using Computational Fluid Dynamics. They depend on the meteorology, the stability of the atmosphere and on the street characteristics. They account for both building and street tree effects. MUNICH can be coupled to a regional-scale chemical transport model to simulate air quality over districts or cities, allowing it to represent the high concentrations of NO2, black carbon, and particles often observed in streets.
