  "term": "Antiproton",
  "field": "Meteorology and atmospheric science",
  "definition": "An elementary particle with the same mass as a proton but with a negative electric charge, constituting the antimatter counterpart to the proton. In atmospheric science, antiprotons are studied as a component of primary cosmic rays that enter the upper atmosphere from space. Their interaction with atmospheric nuclei produces showers of secondary particles that can be detected at the surface.",
