  "term": "Bolometer",
  "field": "Meteorology and atmospheric science",
  "definition": "An instrument designed to measure the intensity of radiant energy by detecting the heat produced when radiation is absorbed by a blackened metal strip or semiconductor. The change in temperature of the absorbing material causes a change in its electrical resistance, which is then measured. Bolometers are used in meteorology for precise measurements of solar and terrestrial radiation.",
