Cloud Properties
General Overview
The Vaisala ceilometer (VCEIL) is a self-contained, ground-based, active, remote-sensing device designed to measure cloud-base height at up to three levels and potential backscatter signals by aerosols. Model CT25K has a maximum vertical range of 25,000 ft.
The ceilometer transmits near-infrared pulses of light, and the receiver detects the light scattered back by clouds and precipitation.
