Howard Penman
Howard Latimer Penman (1909 – 1984) was a British meteorologist. He formulated Penman’s Formula, which is used worldwide by meteorologists and agricultural scientists to assess evaporation rates in different setups (lakes and ponds, lawns, cropped fields) and locations in the world. With John Monteith he formulated the Penman–Monteith equation which is used to calculate evapotranspiration and the need for crop irrigation. Penman was a distinguished Rothamsted Research scientist and government advisor, and a well-known local figure in Harpenden. Early life Howard Penman was born in County Durham and studied at Durham University where he graduated in Physics in 1930. While working for the British Cotton Research Association in Manchester he worked on his thesis for his Ph.D., which was awarded by Durham University in 1938. Bored by the work on cotton dyes he applied in 1937 for a post in the Soil Physics Department at Rothamsted Research, headed by Bernard Keen, for a salar ...

Penman Equation
The Penman equation describes evaporation (''E'') from an open water surface, and was developed by Howard Penman in 1948. Penman's equation requires daily mean temperature, wind speed, air pressure, and solar radiation to predict E. Simpler Hydrometeorological equations continue to be used where obtaining such data is impractical, to give comparable results within specific contexts, e.g. humid vs arid climates. Details Numerous variations of the Penman equation are used to estimate evaporation from water, and land. Specifically the Penman–Monteith equation refines weather based potential evapotranspiration (PET) estimates of vegetated land areas. It is widely regarded as one of the most accurate models, in terms of estimates. The original equation was developed by Howard Penman at the Rothamsted Experimental Station, Harpenden, UK. The equation for evaporation given by Penman is: :E_=\frac where: :''m'' = Slope of the saturation vapor pressure curve (Pa K−1) :''R''n = Ne ...

Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Monteith
John Lennox Monteith DSc, FRS (3 September 1929 – 20 July 2012) was a British scientist who pioneered the application of physics to biology. He was an authority in the related fields of water management for agricultural production, soil physics, micrometeorology, transpiration, and the influence of the natural environment on field crops, horticultural crops, forestry, and animal production. Research His pioneering work with Howard Penman on evapotranspiration is applied worldwide as the Penman-Monteith equation. It predicts evapotranspiration and is recommended by the Food and Agriculture Organization for calculating irrigation quantities. Monteith's research on the role of the environment in agriculture, the physics of crop microclimate, physiology of crop growth and yield, radiation climatology, heat balance in animals, and instrumentation for measuring physical and physiological variables in agriculture has been published in journals throughout the world.
