Abstract

The mixing height (MH), or the height above the surface where pollutants become vertically dispersed, is related to the atmospheric boundary layer (ABL) in homogeneous regions. This layer is characterised by turbulence generated mechanically (from the friction drag of the air moving across the rough and rigid surface of the Earth) and thermally (from the convection process or “bubbling-up” of air parcels from the heated surface). The height of the atmospheric boundary layer (or the depth of surface related influence) is changing in time for a given location depending on the strength of the surface generated mixing and reaches about 1 to 2 km during the day due to heating of the surface by the Sun and about 100 m during the night in conditions of radiative cooling. The boundary layer height changes also depending on the geographical, terrain and vegetation characteristics of a given area [1].
