Constant flux layer

  "id": "MLC-T-MET-004618",
  "term": "Constant flux layer",
  "field": "Meteorology and atmospheric science",
  "definition": "The portion of the atmospheric surface layer, extending from the ground up to about 10% of the boundary layer height, where the vertical turbulent fluxes of momentum, heat, and moisture are assumed to be constant with height. Within this region, the change in flux with altitude is negligible, simplifying the mathematical description of surface-atmosphere exchange processes. This assumption is foundational to Monin-Obukhov similarity theory, which describes profiles of wind and temperature near the surface.",
