Cloud ceilings, the height of the lowest layer of clouds, can be determined using a few different methods. These methods range from visual estimations to sophisticated instruments. Here's an overview:
Methods for Determining Cloud Ceilings
There are two main methods outlined in the provided references for finding cloud ceilings:
- Ceiling Balloons:
- These are special helium balloons.
- They are released into the sky to measure the height of clouds.
- Laser Ceilometers:
- These devices use laser beams.
- A laser ceilometer shoots laser beams upwards.
- When the light hits clouds, small components of light bounce back to the ceilometer. This measures the cloud height.
