Lapse Rate Calculator
Calculates the environmental lapse rate, which is the rate of temperature decrease with increasing altitude in the atmosphere.
Before you use this tool
Use this if
- Calculates the environmental lapse rate, which is the rate of temperature decrease with increasing altitude in the atmosphere.
- You want a calculation that exposes its formula: Lapse Rate = ((T2 - T1) / (h2 - h1)) * 1000 Where: T1 = Temperature at Altitude 1, h1 = Altitude 1, T2 = Temperature at Altitude 2, h2 = Altitude 2
- You already have Temperature at Altitude 1, Altitude 1, Temperature at Altitude 2 values to enter.
Skip this if
- You need an official emergency alert or life-safety instruction.
- You need a certified professional forecast instead of a calculator estimate.
