In 1820 Bellani invented a device for measuring evaporation that was called an atmometer. [3] Modified versions of the Bellani plate evaporimeter are still in use. [4] He invented a hygrometer using a fish bladder in 1836. Another innovation was his pyranometer to measure solar radiation which was a closed glass capsule in which alcohol was ...
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
In 1783, the first hair hygrometer is demonstrated by Horace-Bénédict de Saussure. In 1806, Francis Beaufort introduced his system for classifying wind speeds . [ 4 ] The April 1960 launch of the first successful weather satellite, TIROS-1 , marked the beginning of the age where weather information became available globally.
Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction

Hygrometer: Prototype hygrometers were devised and developed in the hills during the Western Han dynasty in Ancient China to elucidate mechanisms of long-range meteorological fluctuations. [266] The Chinese used a bar of charcoal and a lump of earth: its dry weight was taken and then compared with its damp weight after being exposed in the air.
In meteorology and psychrometrics the word temperature by itself without a prefix usually means dry-bulb temperature. Technically, the temperature registered by the dry-bulb thermometer of a psychrometer. The name implies that the sensing bulb or element is in fact dry. WMO provides a 23-page chapter on the measurement of temperature. [4]
Horace Bénédict de Saussure (French: [ɔʁas benedikt də sosyʁ]; 17 February 1740 – 22 January 1799) was a Genevan [1] geologist, meteorologist, physicist, mountaineer and Alpine explorer, often called the founder of alpinism and modern meteorology, and considered to be the first person to build a successful solar oven.
