Vaisala Ceilometer (VCEIL) - IOP

Instrument Categories: Cloud Properties

General Overview

Picture of the Vaisala Ceilometer (Model CT25K)

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 telescope detects the light scattered back by clouds and precipitation.
