  "term": "Fiducial temperature",
  "field": "Meteorology and atmospheric science",
  "definition": "A specific, precisely known temperature used as a reference for calibrating thermometers or other temperature-measuring devices. This temperature is often associated with a phase transition of a pure substance, such as the triple point of water (273.16 K or 0.01 °C). It provides a stable and reproducible standard for temperature scales.",
