METEOROLOGY – URFACE TEMPERATURE & THERMAL COMFORT CALCULATOR
Road Surface Temperature
A precise tool.
What is the Road Surface Temperature & How does it work?
The temperature of a road surface is influenced by various factors including air temperature, solar radiation, and environmental conditions. Understanding these relationships helps in assessing thermal comfort for pedestrians and vehicles.The road surface temperature can be calculated using the above formula where (T_s) is adjusted based on the absorption of solar radiation by the road surface.
T_s = T_a + alpha Q_r
T_s = Road surface temperature, T_a = Air temperature, alpha = Absorption coefficient, Q_r = Solar radiation

Frequently Asked Questions
How do I calculate road surface temperature?
Use the formula T_s = T_a + Ξ± Q_r, where T_s is the road surface temperature, T_a is air temperature, Ξ± is the absorption coefficient, and Q_r is solar radiation.
What factors affect road surface temperature?
Road surface temperature is influenced by air temperature, solar radiation, and environmental conditions like humidity and wind.
Why is understanding road surface temperature important?
It helps assess thermal comfort for pedestrians and vehicles, ensuring safer and more comfortable travel conditions.
What does the absorption coefficient (Ξ±) represent in this calculation?
The absorption coefficient represents how effectively the road surface absorbs solar radiation.
How can I measure air temperature and solar radiation for this calculation?
Use weather stations or sensors to measure air temperature and solar radiation accurately.
What are typical values for the absorption coefficient (Ξ±) of road surfaces?
Typical values for Ξ± range from 0.8 to 0.9 for dark-colored surfaces and around 0.5 for light-colored surfaces.
Can this calculator be used in urban planning?
Yes, understanding road surface temperatures is crucial for urban planning to improve infrastructure and reduce heat islands.
