Cloud Base Height

A card, similar to battery card that can be on or off, that shows cloud base height. Its a simple calculation based on conditions already collected by Tempest. It may be most relevant to pilots and drone pilots but its an interesting piece of information for all.

“ Once you have determined all of these values, the cloud altitude will be calculated automatically according to the following formula:

cloud base = (temperature - dew point) / 4.4 * 1000 + elevation

In this formula, the temperature and dew point are expressed in degrees Fahrenheits and the elevation and cloud base altitude are expressed in feet. Make sure to adjust the result afterwards if you’re using the SI units!”

Using the surface conditions is not really a reliable way to “calculate” cloud bases… especially in the morning hours.
