instruments can be used to measure properties of the planetary boundary layer, including boundary layer height, aerosols and clouds. Satellite remote sensing...

of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The...

surface layer. Splitting the planetary boundary layer into the surface layer and the Ekman layer generally yields more accurate results. The Ekman layer, with...

aerology is restricted to the free atmosphere, the region above the planetary boundary layer. Early pioneers in the field include Léon Teisserenc de Bort and...

differentiated bodies, the surface is where the crust meets the planetary boundary layer. Anything below this is regarded as being sub-surface or sub-marine...
