Cloud Properties
General Overview
The Vaisala Ceilometer (VCEIL) is a self-contained, ground-based, active, remote-sensing device designed to measure cloud-base height, vertical visibility, and potential backscatter signals by aerosols. It detects up to three cloud layers simultaneously. Model CL31 has a maximum vertical range of 7700 m. The laser ceilometer transmits near-infrared pulses of light and the receiver detects the light scattered back by clouds and precipitation.
