Used by meteorologists to determine the height of the base of the clouds above ground level during day light hours. "Ceiling" refers to the base of the clouds in meteorological terms.

Also called "Cloud Search Light", to measure the height of the clouds base, especially during night.

A type of thermometer used to measure very low temperatures.

Used by meteorologists to identify clouds during sunshine and at night without any difficulty to the eyes.

An instrument used to measure the drop size distribution and velocity of falling hydrometeors.

To obtain a magnifying view of very small objects up to 2000 times. Invented by Reinhold Rudenberg of Germany in 1931.

Fathom meter.

Hygrometer.

Instrument to measure the intensity of radiation.

Gravimeter.

Hydrophone.

Hydroscope. This instrument also indicates atmospheric humidity change.

Hypsometer.

Indicates the formation of ice, frost, or the presence of freezing rain or drizzle.

Light Detection and Ranging. - an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant object.

MECALLI SCALE - used for measuring the intensity of earthquakes. Invented by Guiseppi Mercalli of Italy.

Measuring pressure.

An instrument for measuring the altitude, direction and velocity of movement of clouds.

Measuring thermal radiation and determines the temperature.

Used to measure broad band solar radiance on a planar surface and in a sensor that is designed to measure solar radiation.

Charles Richter of USA in 1935. It is used for measuring the seismic energy released by an earthquake.

Sonic Detection and Ranging - a meteorological instrument which measures the scattering of sound waves by atmospheric turbulence.

A type of Pyranometer - a device used for measuring the combined direct and diffused solar radiation.

An instrumental shelter, a meteorological screen to shield instruments against precipitation and direct heat radiation from outside sources.

SUNSHINE RECORDERS: An instrument to indicate the amount of sunshine at a given location. It gives information on the climate of an area and is useful for science, agriculture and tourism.

A chart recorder that measures and records both temperature and humidity.

Galileo.

An instrument to measure temperature and its gradient. ABU ALI IBN SIHA, also called AVICENNA, is credited with the invention and laterdeveloped by Cornelius Drebbel, Robert Fludd, Galileo and Santorio.

Carries instruments above ground (aloft) to send back information on various aspects of the atmosphere.

A type of radar used to locate precipitation, calculates its motion, estimate its content (rain,snow, hail etc) and forecast its future outcome.

Doppler Radar.

Also called Wind Vane, Cockerel, Weather Cock etc., It is a movable device attached to an elevated object like roof tops, which we normally see every- where, with four semi circular metal cups attached to horizontal bards on a vertical rod. The cups rotate according to the direction of the wind. On top of it we can see a cock (in metal) normally.

Also called Wind Cone. A textile conical tube, to indicate wind direction and speed. Normally found in airports.

A weather observing equipment that uses Radar or sound waves to detect the wind speed and direction. Used for meteorological and aviation purposes.

It is a scale to measure wind speed, it has numbers from 0 to 12. When the scale level reaches 12, it is the highest speed and the phenomenon is termed Hurricane with a wind speed of 118 plus Kmph.
