Answers
Answer:
Explanation:
Anemometer
Element: Wind Speed
Instrument: Anemometer
An instrument which measures wind speed.
Wind Vane
Element: Wind Direction
Instrument: Wind Vane
A device that measures the direction of the wind. It spins on a rod and points in the direction from which the wind blows. The part of the vane that turns into the wind is usually shaped like an arrow. The other end is wide so it will catch the smallest breeze.
Wind Sock
Element: Wind Direction
Instrument: Wind Sock
A light, flexible cylinder or cone mounted on a mast to show the direction and strength of the wind. Wind sock is commonly used at an airport or chemical plant. The cone-shaped bag opened at both ends so that it extends horizontally as the wind blows through it and indicates the wind direction by pointing away from the wind.
Aneroid Barometer
Element: Atmospheric Pressure
Instrument: Aneroid Barometer
A type of barometer used to measure atmospheric pressure.
Digital Barometer
Element: Atmospheric Pressure
Instrument: Digital Barometer
A type of barometer used to measure atmospheric pressure.
Barograph
Element: Atmospheric Pressure
Instrument: Barograph
An instrument that continuously records and provide a graphical representation of atmospheric pressure.
Campbell-Stoke Sunshine Recorder
Element: Sunshine Duration
Instrument: Campbell-Stoke Sunshine Recorder
Campbell-Stokes Pattern Sunshine Recorder employs a glass sphere to focus the sun's rays to an intense spot, which will burn a mark on a curved card mounted concentrically with the sphere. As the earth rotates the position of the spot moves across the card. When the sun is obscured, the trace is interrupted. At the end of the day the total length of the burn or trace, less gaps, equals the duration of sunshine hours.
Ceilometer
Element: Cloud Height
Instrument: Ceilometer
A ceilometer is a device that uses a laser or other light source to determine the height of a cloud ceiling or a cloud base from the ground. Ceilometers can also be used to measure the aerosol concentration within the atmosphere.
Evaporation Pan
Element:
Instrument: Evaporation Pan
A type of evaporation gauge or evaporimeter; it is a pan used in the measurement of the evaporation of water into the atmosphere over specified periods of time.
Hygrometer
Element: Humidity
Instrument: Hygrometer
An instrument used to measure the humidity, or amount of water vapour in the atmosphere. The sensing mechanism of the instrument can be hair (hair hygrometer), a plate coated with carbon (electrical hygrometer), or an infrared sensor (infrared hygrometer).
Psychrometer
Element: Humidity
Instrument: Psychrometer
A hygrometer composed of two similar thermometers. The bulb of one thermometer is kept wet (by means of a thin, wet cloth wick) so that the cooling that results from evaporation makes it register a lower temperature than the dry-bulb thermometer. When readings are taken simultaneously, it is possible (with the use of psychrometric tables) to determine the relative humidity and dew-point temperature of the air.
Thermo-hygrograph
Element: Temperature and Humidity
Instrument: Thermo-hygrograph
An instrument which records the environmental temperature and humidity at the same time, usually both continually.
Stevenson Screen
Element: Temperature and Humidity
Instrument: Stevenson Screen
A standard shelter for housing four types of thermometers: dry, wet, maximum and minimum. The screen shields the instruments from direct sunlight.
Element: Temperature
Instrument: Thermometer
Measures how hot or cold the atmosphere is in (Celsius (C) or Fahrenheit (F), or Kelvin (K)). A traditional thermometer consists of mercury, red spirit or green spirit in a glass tube and operates on the principle that the liquid expands more than the glass does when heated.
Maximum Temperature
Element: Temperature
Instrument: Maximum Temperature
Maximum temperature has historically been measured with a mercury-in-glass thermometer which has a constriction in the neck of the thermometer tube. As the air temperature rises mercury is forced past the constriction. However, as the temperature falls the constriction prevents the mercury from returning to the bulb of the thermometer. The height of mercury in the tube remains at that reached at the hottest time of day. The thermometer is reset by gentle shaking.
