  "term": "Actinometer",
  "field": "Meteorology and atmospheric science",
  "definition": "An instrument used to measure the intensity of solar radiation, particularly the actinic or chemically active portion of the spectrum. It often works by measuring the rate of a photochemical reaction or the heating effect of radiation on a dark surface. Actinometers are employed in meteorology and atmospheric chemistry to quantify the energy available for atmospheric processes.",
