  "term": "Line absorption",
  "field": "Meteorology and atmospheric science",
  "definition": "The absorption of electromagnetic radiation by atmospheric gases at specific, narrow wavelengths, resulting in distinct dark lines in a spectrum. This phenomenon occurs when photons possess the exact energy required to excite an atom or molecule to a higher energy state. Each gas has a unique spectral fingerprint of absorption lines, used for remote sensing.",
