  "term": "Chapman layer",
  "field": "Meteorology and atmospheric science",
  "definition": "A theoretical model describing the vertical distribution of an ionized layer in a planetary atmosphere, formed by the absorption of monochromatic radiation. It predicts a layer with a maximum electron density at a specific altitude, decreasing above and below this peak. This model is used to understand the formation of the Earth's ionosphere, particularly the E and F1 regions.",
