Lapse Rate Calculator

The lapse rate ($L$) is defined as the rate at which the temperature of an air parcel changes with respect to a change in altitude. The lapse rate is a crucial parameter in atmospheric science, meteorology, and aviation, as it influences the stability of the atmosphere and plays a role in various weather phenomena. The negative sign indicates that, in the troposphere, temperature generally decreases with an increase in altitude. Mathematically, it is expressed as:

Where:

• T_h​ is the temperature at altitude 
• T₀​ is the temperature at sea level (or another reference altitude ℎ0h0​),
• h_h​ is the higher altitude,
• h₀​ is the reference altitude
