Until the 18 th century, people were utterly dependent on sensory observations for any weather data, i. Now, the time has changed. Today, we are blessed by modern technology which includes different weather instruments that help us to accumulate accurate weather data.
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature , atmospheric pressure , humidity , wind speed , wind direction , and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature SST , wave height, and wave period.

Ask: What instruments do you or your family members use to measure weather? What instruments do scientists use to measure weather? Students will likely be able to name a thermometer, but they may not be able to name any other instruments that measure weather. Explain to students that there are many more tools scientists use to measure weather. They even use their eyes as important instruments for measuring visibility and making observations.
Meteorologists use a wide variety of different instruments to measure weather conditions, but many of these instruments fall into relatively common, overarching categories. Thermometers, for instance, come in traditional liquid-in-glass forms and newer electronic forms, but both measure temperature in Celsius and Fahrenheit. Other instruments measure aspects of weather like rainfall, pressure, humidity and wind speed. These instruments and measurements allow meteorologists to make predictions on weather conditions in the near future. Thermometers measure the high and low outdoor temperatures in degrees Fahrenheit and degrees Celsius.
This page provides some information about the Bureau's observation of the weather which may help you selecting the type of data you require. It briefly provides information about where you may find a Bureau weather station , what observations may have been made and why they differ between stations, and why there can be a different number of observations available within a day. Weather data are obtained from different types of observing stations around Australia, on offshore islands, and in the Antarctic. They include Bureau-staffed and cooperative observer stations, automatic weather stations, meteorological satellites and drifting ocean buoys, ships and aircraft that collect weather data. Station locations are chosen based on a range of different requirements PDF, kB and constraints, including:.

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.
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries.
Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube.
