No. An anemometer measures wind speed. A ceilometer measures the height of cloud base.
A ceilometer is commonly used to measure the vertical distance of the base of clouds above ground level. It works by emitting laser pulses or light beams vertically upwards and measuring the time it takes for the light to reflect back from the cloud base.
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
