The Skyliner

T-Td x 322=cb

Temperature minus dewpoint (temperature), times three hundred and twenty two (feet), equals cloud base.

Skyliner continously runs that familiar meteorological formula with a real-time linear computer

LINC

Electronic sensors gather information to generate a cloud base altitude from the three most important atmospheric components

Air Temperature
Relative Humidity
Dewpoint (temperature)

Using these values Skyliner computes the dewpoint (temperature) and then the altitude of the dewpoint, which is the cloud base. If the cloud base is at "0" feet of altitude, then it's fog.

Look at the sky on a nice day with some puffy low clouds just above. Notice the distinctive straight line across the bottom of the clouds as you look out to the horizon. On most fair-weather days the cloud base will be at about 3500 feet.
