  "id": "MLC-T-MET-005498",
  "term": "Exchange coefficients",
  "field": "Meteorology and atmospheric science",
  "definition": "Dimensionless parameters that quantify the efficiency of turbulent transfer of momentum, heat, and moisture between the Earth's surface and the atmosphere. These coefficients relate the fluxes of these quantities to the mean gradients of wind speed, temperature, and humidity. They are used in atmospheric models to parameterize boundary layer processes and surface-atmosphere interactions.",
