  "id": "MLC-T-MET-006214",
  "term": "Helical scanning",
  "field": "Meteorology and atmospheric science",
  "definition": "A radar scanning technique where the antenna continuously rotates in azimuth while simultaneously elevating or depressing its angle, tracing a helical path through the atmosphere. This method allows for rapid and efficient volumetric sampling of the atmosphere, providing a three-dimensional view of precipitation and wind fields. It is commonly used in modern Doppler weather radars.",
