Meteorological instruments are the equipments used to sample the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment. Meteorology, however, is a science which does not use much lab equipment but relies more on on-site observation and remote sensing equipment. In science, an observation, or observable , is an abstract idea that can be measured and for which data can be taken. Rain was one of the first quantities to be measured historically. Two other accurately measured weather -related variables are wind and humidity. Many attempts had been made prior to the 15th century to construct adequate equipment to measure atmospheric variables.

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. Meteorologists first used liquid-in-glass thermometers in the late s, but they now use electronic maximum-minimum temperature sensor systems more frequently.

This book describes the fundamental scientific principles underlying high quality instrumentation used for environmental measurements.

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. Drifting weather buoys outnumber their moored versions by a significant amount.

His research focuses on one of the oldest experimental topics in meteorology, atmospheric electricity and the development of new surface and balloon-carried instruments for environmental measurements.
