Planetary Boundary Layer (PBL): The lowest part of the atmosphere that is directly influenced by the earth’s surface, characterised by turbulent mixing and diurnal cycles.

The planetary boundary layer (PBL) is a critical component of the Earth’s atmosphere, governing the exchange of momentum, heat, moisture and pollutants between the surface and the free atmosphere.
