Peplosphere is a rarely used term that refers to the ground-based layer of the which is affected by convection during the day, or alternatively, to the region of friction between the atmosphere and the Earth's surface.
If distinguished from the free atmosphere, the peplosphere reaches up to about 2 km of height, depending on the (underlying hills and mountains).
The Peplosphere is topped by the peplopause which often coincides with an inversion layer. At night when the boundary layer becomes stable and its thickness shrinks, a neutrally stratified layer remains below the peplopause. This layer acts as a reservoir for air pollutants which were vertically mixed during the day. Therefore the nightly layer above the boundary layer and below the peplopause is sometimes called "reservoir layer".
The Peplosphere corresponds to or includes the atmospheric boundary layer, or planetary boundary layer (PBL)
