  "id": "MLC-T-MET-010218",
  "term": "Wet-bulb depression",
  "field": "Meteorology and atmospheric science",
  "definition": "The difference between the dry-bulb temperature and the wet-bulb temperature at a given time and place. This value is an indicator of atmospheric moisture content; a larger depression signifies lower relative humidity, as there is more potential for evaporative cooling. When the air is saturated (100% relative humidity), the wet-bulb depression is zero because the dry-bulb and wet-bulb temperatures are equal.",
