The Model
of Urban Network of Intersecting Canyons and Highways (MUNICH)
MUNICH is used to simulate subgrid concentrations in
the urban canopy represented by the street network.
Model description
MUNICH consists of two main components:
(1) the street-canyon component, which represents the atmospheric processes in the volume of the
urban canopy, and
(2) the street-intersection component, which represents the processes in the
volume of the intersection.
These components can be connected to regional models (Polair3D, Chimere, etc) at roof level and are also interconnected. A detailed description is found at Hands-on session for MUNICH
Simulated NOx concentrations using MUNICH (a) during nighttime at 1 AM (UTC) (b) in the morning rush-hour at 7 AM (UTC)
on March 25, 2014.
