The ceilometer that is currently deployed on Deebles Point is purchased from Jenoptik. Using the LIDAR technique it measures the backscattered energy from particles within its narrow beam, which can be either cloud droplets or atmospheric aerosol. It operates with a 1024 nm wavelength up to heights of 15 km with a resolution of 15 m.

Ceilometers are very useful for detecting cloud edges and the ceilometer backscatter profiles collected on Deebles Point are used to derive cloud base heights, which can be done for up to three layers. In practice, the beam is  attenuated quickly after having penetrated a cloudy layer. An example of the backscatter profiles (ln[PR^2]) for one day of measurements in June is shown in the below figure, with black dots indicate the derived cloud base heights.
