  "term": "Diffusion coefficient",
  "field": "Meteorology and atmospheric science",
  "definition": "A proportionality constant that quantifies the rate at which a substance diffuses through a medium. It relates the flux of a substance to its concentration gradient, as described by Fick's laws of diffusion. This coefficient is typically measured in units of square meters per second (m²/s).",
