anemometer used for measuring wind speed common weather station instrument from the Greek word anemos means wind Battista Alberti in 1450 Weather vane Also known as wind vane and weathercock showing the direction of the wind used as an architectural ornament to the highest point of a building. Windsock conical textile tube indicates wind direction and speed. used at airports chemical plants highways Wind

Barometer instrument that measures atmospheric pressure Creator of mercury barometer unknown Creator of aneroid barometer is 1844 by Lucien Vidi barograph recording aneroid barometer A barograph is used to measure pressure It produces paper or foil chart called barogram records the air pressure every 3 hours Creator is Lucien Vidi Air Pressure

radiosonde Battery-powered instrument Carried into the atmosphere by a weather balloon Measures various atmospheric parameters Transmits by radio to a ground receiver. Modern Weather Instruments Weather balloon Made of highly flexible latex material Usually filled with hydrogen or helium Weather satellite used to monitor the weather and climate of the Earth. Sees clouds and cloud systems City lights, fires, effects of pollution, auroras etc

Modern Weather Instruments Weather radars used in locating precipitation calculating its motion estimate its type Most are Doppler radars ASOS Automated sensor suites Designed to serve aviation For safe and efficient aviation operations Designed to measure: Wind speed and direction Visibility Present weather; etc
