  "id": "MLC-T-MET-004172",
  "term": "Carbon-film hygrometer element",
  "field": "Meteorology and atmospheric science",
  "definition": "A sensor component used to measure atmospheric humidity, consisting of a thin film of carbon particles suspended in a hygroscopic binder on a substrate. As the element absorbs or releases water vapor, its electrical resistance changes in a way that can be calibrated to relative humidity. This type of sensor is widely used in radiosondes for upper-air soundings because of its rapid response time and low cost.",
