planetary boundary layer

[′plan·ə‚ter·ē ′bau̇n·drē ‚lā·ər]
(meteorology)
That layer of the atmosphere from the earth's surface to the geostrophic wind level, including, therefore, the surface boundary layer and the Ekman layer; above this layer lies the free atmosphere.

Improved understanding and realistic modeling of coastal processes are also necessary for accurate wind resource assessment and wind forecasting, yet current numerical weather prediction models and their parameterizations of the planetary boundary layer (PBL) have not been comprehensively evaluated in this offshore area.

The energy at the ocean exchange and supply through the planetary boundary layer to the free atmosphere play an important role in the intensification of the TC [12].
Two recent documents (NRC 2009,2010) concluded that the structure and variability of the lower troposphere is currently not well known because vertical profiles of water vapor, temperature, and winds are not systematically observed and that this lack of observations results in the planetary boundary layer being the single most important undersampled part of the atmosphere.
