Here's how it works:
* Ceilometers use a laser or light beam to measure the distance to the base of the cloud. The beam is directed upwards, and the time it takes for the light to return after reflecting off the cloud base is measured.
* The distance to the cloud is then calculated based on the speed of light. This provides a measurement of the cloud base height.
Ceilometers are essential for aviation safety, as they provide pilots with crucial information about cloud conditions, allowing them to make informed decisions about flight paths and altitudes.
