  "term": "Beamwidth",
  "field": "Meteorology and atmospheric science",
  "definition": "The angular width of a radar or lidar beam, defined as the angle between the half-power points of the main lobe of the antenna radiation pattern. It quantifies the spatial resolution of the instrument, indicating the extent over which the emitted energy is concentrated. A narrower beamwidth provides finer spatial detail in atmospheric measurements, such as precipitation or aerosol distributions.",
