  "id": "MLC-T-MET-006792",
  "term": "Klydonograph",
  "field": "Meteorology and atmospheric science",
  "definition": "An instrument that records the polarity and approximate magnitude of transient high-voltage surges, such as those caused by lightning strikes on power lines. It operates by placing an electrode against a photographic plate or film, where a voltage surge creates a distinctive discharge pattern known as a Lichtenberg figure. The size and shape of the figure indicate the peak voltage and polarity of the surge, providing data for atmospheric electricity and lightning protection studies.",
