METEOROLOGY – OLAR RADIATION CALCULATOR
Longwave Radiation Up
A precise tool.
What is the Longwave Radiation Up & How does it work?
Longwave radiation, also known as infrared radiation, is emitted by the Earth’s surface and atmosphere. This type of radiation is primarily dependent on the temperature of the emitting body.
The Stefan-Boltzmann law describes the relationship between the temperature of a blackbody and its total energy radiated per unit surface area. The formula for outgoing longwave radiation (L) is given by:
The Stefan-Boltzmann law describes the relationship between the temperature of a blackbody and its total energy radiated per unit surface area. The formula for outgoing longwave radiation (L) is given by:
L = sigma T^4
L = Outgoing longwave radiation
sigma = Stefan-Boltzmann constant (5.67 Γ 10β»βΈ W mβ»Β² Kβ»β΄)
T = Absolute temperature in Kelvin

Frequently Asked Questions
What is longwave radiation?
Longwave radiation, or infrared radiation, is emitted by the Earth’s surface and atmosphere due to its temperature.
How does temperature affect outgoing longwave radiation?
Temperature significantly affects outgoing longwave radiation. Higher temperatures result in more radiation being emitted according to the Stefan-Boltzmann law.
What is the Stefan-Boltzmann constant?
The Stefan-Boltzmann constant (Ο) is 5.67 Γ 10β»βΈ W mβ»Β² Kβ»β΄, used in calculating the total energy radiated per unit surface area.
How do I use this calculator?
Input the temperature of the emitting body into the calculator to determine the outgoing longwave radiation using the Stefan-Boltzmann law.
What is the formula for outgoing longwave radiation?
The formula for outgoing longwave radiation (L) is L = Ο Tβ΄, where Ο is the Stefan-Boltzmann constant and T is the temperature in Kelvin.
Why is this important in meteorology?
Understanding outgoing longwave radiation is crucial in meteorology as it affects global energy balance, climate patterns, and weather conditions.
Can I use this calculator for any object?
Yes, you can use this calculator for any blackbody object by providing its temperature to determine the outgoing longwave radiation.
