What is the approximate value for the Dry Adiabatic Lapse Rate (DALR) in the atmosphere?

💡 Explanation:

The Dry Adiabatic Lapse Rate (DALR) is the rate at which the temperature of an unsaturated parcel of air decreases as it rises in the atmosphere. The universally accepted value for DALR is approximately 9.8°C per 1,000 meters (or 1°C per 100m). The other values are: 6.5°C/1,000m (the average Environmental Lapse Rate - ELR) and 5.5°C/1,000m (a common estimate for the Saturated or Moist Adiabatic Lapse Rate - MALR).
