Rain Gauge
A rain gauge (also known as udometer, pluvia metior, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation (meteorology), precipitation over a predefined area, over a period of time. It is used to determine the depth of precipitation (usually in mm) that occurs over a unit area and measure rainfall amount. History The first known rainfall records were kept by the Ancient Greece, Ancient Greeks, at around 500 BCE. People living in India began to record rainfall in 400 BCE Ian Strangeways, A History of rain gauges, TerraData, 2010 The readings were correlated against expected growth. In the Arthashastra, used for example in Magadha, precise standards were set as to grain production. Each state storehouse was equipped with a rain gauge to classify land for taxation purposes..Rainfall measurement was also mentioned in the Jewish text in Palestine. In 1247, the Song (Chinese surname), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christopher Wren
Sir Christopher Wren PRS FRS (; – ) was one of the most highly acclaimed English architects in history, as well as an anatomist, astronomer, geometer, and mathematician-physicist. He was accorded responsibility for rebuilding 52 churches in the City of London after the Great Fire in 1666, including what is regarded as his masterpiece, St Paul's Cathedral, on Ludgate Hill, completed in 1710. The principal creative responsibility for a number of the churches is now more commonly attributed to others in his office, especially Nicholas Hawksmoor. Other notable buildings by Wren include the Royal Hospital Chelsea, the Old Royal Naval College, Greenwich, and the south front of Hampton Court Palace. Educated in Latin and Aristotelian physics at the University of Oxford, Wren was a founder of the Royal Society and served as its president from 1680 to 1682. His scientific work was highly regarded by Isaac Newton and Blaise Pascal. Life and works Wren was born in East Knoyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George James Symons
George James Symons Fellow of the Royal Society, FRS (6 August 1838 – 10 March 1900) was a British meteorologist who founded and managed the ''British Rainfall Organisation'', an unusually dense and widely distributed network of rainfall data collection sites throughout the British Isles. Life He was the only child of Joseph Symons by his wife, Georgina Moon. He was born at Queen's Row, Pimlico, on 6 August 1838. His education, begun at St. Peter's collegiate school, Eaton Square, was completed under private tuition at Thornton rectory, Leicestershire. He subsequently passed with distinction through the course at the school of mines, Jermyn Street. From boyhood, he made observations on the weather with instruments of his own construction, and at the age of seventeen became a member of the Royal Meteorological Society. From 1863, he sat on the council, acted as secretary 1873-9 and 1882-99, and was elected president in 1880 and again in 1900. In 1857, he undertook, and con ...

Atmospheric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760mm Hg, 29.9212 inchesHg, or 14.696psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's gravi ...

Thomas Barker (meteorologist)
Thomas Barker (1722 – 29 December 1809) was a Rutland squire who kept a detailed weather record at Lyndon Hall from 1736 to 1798. Life and work Thomas Barker was born at Lyndon Hall, Lyndon, Rutland, England in 1722. The son of Samuel Barker and grandson of William Whiston, he came from a distinguished local family, which had lived in Lyndon from the time of Henry VIII. He married Anne White, sister of Gilbert White the famous naturalist. The couple had five children, a son and four daughters. Thomas Barker was a vegetarian, having discovered in early childhood that his constitution was unsuited to the consumption of meat. Barker's meteorological records have proved a valuable resource for those researching the 18th century British climate, because of its early date for instrumental observations, its length and the meticulousness with which it was compiled. He recorded barometric pressure, temperature, clouds, wind and rainfall. (In the early years his thermometer was in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbert White
Gilbert White FRS (18 July 1720 – 26 June 1793) was a " parson-naturalist", a pioneering English naturalist, ecologist, and ornithologist. He is best known for his ''Natural History and Antiquities of Selborne''. Life White was born on 18 July 1720 in his grandfather's vicarage at Selborne in Hampshire. His grandfather, also Gilbert White was at that time vicar of Selborne. Gilbert White's parents were John White (1688–1758) a trained barrister and Anne Holt (d. 1740). Gilbert was the eldest of eight surviving siblings, Thomas (b. 1724), Benjamin (b. 1725), Rebecca (b. 1726), John (b. 1727), Francis (b. 1728/29), Anne (b. 1731), and Henry (b. 1733). Gilbert's family lived briefly at Compton, Surrey, before moving into 'The Wakes' in 1728, that was to be his home for the rest of his long life. Gilbert White was educated in Basingstoke by Thomas Warton, father of Joseph Warton and Thomas Warton, who would have been Gilbert's school fellows. There are also suggestion ...
