  "id": "MLC-T-MET-005876",
  "term": "Gas thermometer",
  "field": "Meteorology and atmospheric science",
  "definition": "A device that measures temperature by observing the pressure or volume changes of a fixed amount of gas. It operates on the principle that the pressure of a gas at constant volume, or its volume at constant pressure, is directly proportional to its absolute temperature. This instrument is often used as a primary standard for temperature measurement due to its high accuracy.",
