  "field": "Meteorology and atmospheric science",
  "definition": "A distinct dark or bright line in an otherwise continuous spectrum, caused by the absorption or emission of electromagnetic radiation at a specific wavelength by atoms or molecules. In atmospheric science, spectral lines from gases like oxygen, water vapor, and carbon dioxide are used to identify and quantify their presence. The position and intensity of these lines provide information about the composition and temperature of the atmosphere.",
