Determine the surface temperature.
Determine the DEW POINT Temperature (psychrometer, hygrometer, etc)
Find the difference between the two temperatures.
Divide the difference by the DRY ADIABATIC LAPSE RATE
(5.5 degrees/1000feet)
The result will be the height of the cloud base above the surface in thousands of feet.

Cloud Base Altitude

For convective cloud, cumulus and cumulonimbus, subtract the dewpoint from the temperature to get the dewpoint depression. Multiply this figure by 400ft to get the height of the cloud base. Thus
Temperature 25°C
Dewpoint 17°C
Dewpoint depression 8°C
8 X 400ft = 3200ft
The base of non-convective cloud can be determined using an electronic sounder; using a cloud-base searchlight at night; putting a balloon up into it; determining the height from an aerological diagram; asking a friendly pilot; or making an educated guess.
