ceilometers measure cloud heights.
The ceilometer instrument.
Laser Ceilometer
No. An anemometer measures wind speed. A ceilometer measures the height of cloud base.
Feet, eg, 3 foot. 1 foot = 12 inches 3 feet = 1 yard
Data from a radiosonde will give an indication of cloud height. Also, cloud base can be measured using a laser device. In many parts of the world, where equipment is expensive, and in fairly recent times before such equipment was commonly available, observers estimated cloud height.
There are several instruments used to predict the weather in most cases, but the ones that determine whether there will or will not be rain are:Barometer - measures air pressurePsychrometer - measures relative humidityAnemometer - measures wind speedWeather maps - used by meteorologists to collect dataWeather satellites - used to track large-scale air movements; the data these collect are analyzed by meteorologists and computers
