  "field": "Meteorology and atmospheric science",
  "definition": "A dimensionless measure of the transparency of a medium, indicating how much light is absorbed or scattered as it passes through. It quantifies the extinction of radiation due to absorption and scattering processes within a given path. A higher optical depth signifies greater attenuation of radiation.",
