I am interested in modelling air transport in the boundary layer (BL) at O(100m-1km) resolution. At these resolutions BL turbulence is partially resolved and the modelling regime is in the so-called "greyzone" of BL turbulence. Turbulence controls dispersion in the BL and therefore its representation is important for accurate urban air quality prediction. My PhD research questions are:
- How does model resolution in the greyzone influence urban pollution dispersion prediction?
- What effect does the urban canopy have on urban pollution dispersion?
- Is it necessary to represent the urban canopy in the vertical rather than as a 0D slab for accurate air quality prediction?
- What are the important meteorological conditions affecting urban air quality?
