  "term": "Reanalysis",
  "field": "Meteorology and atmospheric science",
  "definition": "A systematic process of reprocessing historical meteorological observations using a fixed, modern numerical weather prediction model and data assimilation system. This creates a consistent, long-term record of atmospheric and oceanic variables, free from changes in observing systems or model physics over time. Reanalysis datasets are widely used for climate research and model validation.",
