  "term": "Balance year",
  "field": "Meteorology and atmospheric science",
  "definition": "The 12-month period over which the mass balance of a glacier or ice sheet is calculated, representing a full cycle of accumulation and ablation. The period does not necessarily align with the calendar year, instead beginning and ending at the point of minimum mass, usually in late summer. A positive balance year indicates net ice gain, while a negative balance year signifies net ice loss.",
