This calculator requires the use of Javascript enabled and capable browsers. This calculator is designed to approximate the altitude of a cloud mass and the temperature within it. Select the temperature designation and the distance (altitude) designation for calculation. Enter the ambient air temperature and dewpoint. If you are unsure of the dewpoint, you can determine it with our Dew Point And Relative Humidity Calculator. Click on Calculate.
The calculated data is based on the assumption from standard conditions that the air temperature drops 9.84 degrees C per 1000 m of altitude and the dewpoint drops 1.82 degrees C per 1000 meters altitude. Here is more information of Celsius, Fahrenheit, Kelvin, Réaumur, and Rankine Temperature Conversion. The following formulas are used to estimate cloud height
and temperature.
cloudTemp = - 0.00984*cloudHeight + airTemp
cloudTemp = - 0.00182*cloudHeight + dewPoint
