METEOROLOGY – URFACE TEMPERATURE & THERMAL COMFORT CALCULATOR
Screen Temperature Correction
A precise tool.
What is the Screen Temperature Correction & How does it work?
Screen temperature correction is essential for accurate weather measurements, especially at different elevations. The atmospheric pressure decreases with height, affecting the temperature readings from standard thermometers.
The formula to correct screen temperature for elevation is given by:This correction accounts for the adiabatic cooling effect of air as it rises.
The formula to correct screen temperature for elevation is given by:
T_{corrected} = T_{screen} – 0.0065 times H
T_{corrected} = Corrected screen temperature (°C)
T_{screen} = Measured screen temperature (°C)
H = Height above sea level (m)
T_{screen} = Measured screen temperature (°C)
H = Height above sea level (m)

Frequently Asked Questions
How does atmospheric pressure affect temperature readings?
Atmospheric pressure decreases with height, which affects the temperature readings from standard thermometers.
What is the formula for screen temperature correction?
The formula is T_corrected = T_screen – 0.0065 * H, where T_corrected is the corrected screen temperature (°C), T_screen is the measured screen temperature (°C), and H is the height above sea level (m).
Why is screen temperature correction important?
Screen temperature correction is essential for accurate weather measurements, especially at different elevations.
What does the adiabat account for in this correction?
The adiabat accounts for the change in temperature with height due to atmospheric pressure changes.
How do I use this calculator?
Input the measured screen temperature and the height above sea level into the calculator to get the corrected screen temperature.
What is the significance of the 0.0065 factor in the formula?
The 0.0065 factor represents the average rate of temperature decrease with altitude in the troposphere, known as the adiabatic lapse rate.
Can this correction be applied to all types of thermometers?
This correction is specifically designed for standard thermometers used in meteorology and climate studies.
