  "term": "Tau-value",
  "field": "Meteorology and atmospheric science",
  "definition": "A dimensionless parameter representing the optical thickness or optical depth of a medium, such as a cloud or aerosol layer, to radiation. It quantifies the extent to which radiation is attenuated by absorption and scattering as it passes through the medium. A higher tau-value indicates greater attenuation.",
