  "id": "MLC-T-MET-008424",
  "term": "Rayleigh optical depth",
  "field": "Meteorology and atmospheric science",
  "definition": "A measure of the optical thickness of an atmosphere due to Rayleigh scattering by air molecules. It represents the total attenuation of light passing through a column of the atmosphere solely due to molecular scattering, ignoring aerosols and clouds. This value is wavelength-dependent, with shorter wavelengths experiencing greater scattering.",
