  "id": "MLC-T-MET-004736",
  "term": "Counter-gradient flux",
  "field": "Meteorology and atmospheric science",
  "definition": "A net transport of a scalar quantity, such as heat or moisture, that occurs in the direction of increasing mean concentration or temperature. This phenomenon is contrary to the typical down-gradient diffusion driven by Fick's law. It is often associated with organized turbulent structures in the atmospheric boundary layer.",
