Noise threshold

  "id": "MLC-T-MET-007567",
  "term": "Noise threshold",
  "field": "Meteorology and atmospheric science",
  "definition": "The minimum power or intensity level that a signal must exceed to be distinguished from background noise by a sensor or data processing algorithm. Signals below this level are considered part of the noise and are filtered out or ignored. In weather radar data, setting a noise threshold prevents the display of spurious, non-meteorological echoes caused by receiver noise.",
