  "id": "MLC-T-MET-006884",
  "term": "Laser ceilometer",
  "field": "Meteorology and atmospheric science",
  "definition": "An instrument that uses a laser beam to determine cloud base height by measuring the time it takes for a pulse of light to travel from the instrument to the cloud base and back. It emits a vertical laser pulse and detects the backscattered signal from cloud droplets or ice crystals. Modern ceilometers can often detect multiple cloud layers and provide vertical visibility information.",
