Where is a ceilometer placed?
The ceilometer consists essentially of a projector, a detector, and a recorder. The projector emits an intense beam of light into the sky. The detector, located at a fixed distance from the projector, uses a photoelectric cell to detect the projected light when it is reflected from clouds.
What does a ceilometer look like?
It consists essentially of a rotating projector, a detector, and a recorder. The projector emits an intense beam of light above into the sky at an angle that varies with the rotation. The detector, which is located at a fixed distance from the projector, uses a photodetector pointing vertically.
Who invented the ceilometer?
meteorologist Poul la Cour
As will be retold here, the principle was demonstrated as early as 1871 by the Danish meteorologist Poul la Cour, who is the likely inventor of the ceilometer.
What is ceilometer OpenStack?
The Ceilometer project is a data collection service that provides the ability to normalise and transform data across all current OpenStack core components with work underway to support future OpenStack components. Ceilometer is a component of the Telemetry project.
What is the use of a ceilometer?
A ceilometer is an automatic, active, remote-sensing instrument for detecting the presence of clouds overhead and measuring the height of their bases. It was used at meteorological stations and airports to continuously measure cloud height above the ground and indicate that reading on a display unit.
How do you use a ceilometer?
The rotating-transmitter ceilometer has its separate receiver fixed to direct reflections only from directly overhead while the transmitter sweeps the sky. When the modulated beam intersects a cloud base directly over the receiver, light is reflected downward and detected.
What is ceilometer in geography?
ceilometer, device for measuring the height of cloud bases and overall cloud thickness. When a reflection is detected, the ceilometer measures the vertical angle to the spot; a simple trigonometric calculation then yields the height of the cloud ceiling.
What is a Ceilometer used for?
ceilometer, device for measuring the height of cloud bases and overall cloud thickness. One important use of the ceilometer is to determine cloud ceilings at airports.
What is OpenStack panko?
Panko is designed to provide a metadata indexing, event storage service which enables users to capture the state information of OpenStack resources at a given time. Its aim is to enable a scalable means of storing both short and long term data for use cases such as auditing and system debugging.
