  "term": "Protected thermometer",
  "field": "Meteorology and atmospheric science",
  "definition": "A thermometer shielded from direct solar radiation, precipitation, and thermal radiation from surrounding objects to measure ambient air temperature accurately. The protection is provided by a louvered enclosure, such as a Stevenson screen, which permits free air circulation around the sensor. Unprotected thermometers exposed to direct sunlight will record temperatures significantly higher than the actual air temperature.",
