  "id": "MLC-T-MET-008657",
  "term": "Saturation deficit",
  "field": "Meteorology and atmospheric science",
  "definition": "The difference between the amount of water vapor required to saturate the air at a given temperature and the actual amount of water vapor present. It represents the capacity of the air to hold additional moisture before reaching saturation. A larger saturation deficit indicates drier air and a greater potential for evaporation.",
