  "term": "Model Calibration",
  "field": "Environment",
  "definition": "1. Refinement of mathematical model parameters and coefficients through comparison to data by making scientifically consistent and rational adjustments.\n\n2. The process of adjusting model parameters within physically defensible ranges until the resulting predictions give the best possible fit to the observed data (EPA 1994b). In some disciplines, calibration is also referred to as “parameter estimation” (Beck et al. 1994).",
