  "term": "Environmental lapse rate",
  "field": "Meteorology and atmospheric science",
  "definitions": [
    "The rate at which the actual temperature of the atmosphere decreases with increasing altitude at a given time and location. This rate is measured by instruments such as radiosondes and varies significantly with atmospheric stability and weather conditions. A typical average value for the troposphere is about 6.5 degrees Celsius per kilometer.",
    "The rate of decrease of air temperature with height, usually measured with a radiosonde."
