  "id": "MLC-T-MET-004551",
  "term": "Complex index of refraction",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical representation of how electromagnetic radiation propagates through a medium, accounting for both the phase speed and the attenuation of the wave. The real part describes the phase velocity, while the imaginary part quantifies the absorption or scattering of the radiation. This index is particularly relevant for understanding light interaction with aerosols and clouds in the atmosphere.",
