Ceilometer

Ceilometer A Ceilometer is a device using a laser or other light source to determine the height of a cloud base.

ceilometer"An automatic, active, remote-sensing instrument for detecting the presence of clouds overhead and measuring the height of their bases.

Ceilometer - an automatic, recording, cloud-height indicator. A light is projected upward onto the cloud base; the reflected light is detected by a photocell, and the height is determined by triangulation (the unique point where three line meet).

CEILOMETER: Instrument used to measure cloud base height. CELSIUS: A temperature scale having the freezing point of pure water at 0° and the boiling point at 100° under standard sea level pressure.

ceilometer: an instrument used to measure cloud height. Celsius: term used to describe temperature based on the boiling point (100°) and the freezing point (0°) of pure water at sea level.

Ceilometer: a device using a laser or other light source to determine the height of a cloud base.

Ceilometer - An instrument that automatically records cloud height. Celsius Scale - A temperature scale where zero is assigned to the temperature where water freezes and 100 to the temperature where water boils (at sea level).

ceilometer—A cloud-height measuring system. It projects light on the cloud, detects the reflection by a photoelectric cell, and determines height by triangulation.

Ceilometer- A device used to evaluate the height of clouds or the vertical visibility into a surface-based obscuration.

Ceilometer An instrument that automatically records cloud height. Centrifugal forceA force directed outward, away from the center of a rotating object; equal in magnitude to the centripetal force but in the opposite direction.

C0300 Ceilometer Cloud height meter Instrument for measuring the height of the base of a cloud layer, with or without a recording device. C0310 Cellini's halo (H0460) ...

CEILOMETER An instrument that is used to measure the angular elevation of a projected light on the base of a cloud.

Fixed-beam ceilometer See ceilometer. Flight forecast An aviation weather forecast for a specific flight. Float barograph A type of recording siphon barometer.

BeltIn hydrologic terms, the area between lines drawn tangential to the extreme limits of fully developed meandersMeasured CeilingA ceiling classification applied when the ceiling value has been determined by an instrument, such as a ceilometer or ...

Ceilometer: An instrument for measueing cloud heights usually located at the end of an airport runway. 7. Clinometer: An instrument used with a ceiling light or clinometer at night for measueing cloud heights. 8.

MEASURED CEILING A ceiling classification applied when the ceiling value has been determined by an instrument, such as a ceilometer or ceiling light, or by the known heights of unobscured portions of objects, other than natural landmarks, ...

A ceiling classification applied when the ceiling value has been determined by an instrument, such as a ceilometer or ceiling light, or by the known heights of unobscured portions of objects, other than natural landmarks, near the runway.

Ceiling- The height of the lowest layer of clouds when the sky is more than 6/10ths covered. A ceilometer is the instrument that measures and records cloud heights.
