Aspiration thermograph

  "id": "MLC-T-MET-003651",
  "term": "Aspiration thermograph",
  "field": "Meteorology and atmospheric science",
  "definition": "A recording thermometer that actively draws air over its temperature-sensing element to provide a more accurate and continuous record of air temperature. The forced ventilation minimizes errors from solar radiation and stagnant air, which can otherwise affect the sensor's reading. This instrument produces a continuous trace of temperature over time, often on a rotating drum.",
