Frank Pasquill FRS[1] (8 September 1914 – 15 October 1994) was an English meteorologist at the Meteorological Office who worked throughout his career in the field of atmospheric diffusion and micrometeorology.
He conducted field measurements on evaporation and obtained vertical profiles of the turbulent fluxes of heat and water vapor.
In 1954, he returned to Porton Down to conduct field measurements on the structure of atmospheric turbulence and the dispersion of pollutants.
He developed a simple method for assessing atmospheric stability based on wind speed, solar radiation, cloud cover, and time of day.
He was promoted to Deputy Chief Scientific Officer in 1966 and in 1970 headed a research branch in boundary-layer meteorology.
At these institutions, he worked with Hans Panofsky, Kenneth Calder, Frank Gifford, and Robert McCormick.
He was elected an Honorary Member of the Royal Meteorological Society in 1978 and was awarded its Symons Gold Medal in 1982.
