  "id": "MLC-T-MET-007721",
  "term": "Optimum interpolation",
  "field": "Meteorology and atmospheric science",
  "definition": "A statistical data assimilation technique used to estimate the value of a meteorological variable at unobserved locations by combining observations with a background field. It minimizes the mean square error of the analysis by weighting observations according to their accuracy and spatial correlation. This method is a precursor to more advanced techniques like the Kalman filter.",
