langleyn.

Brit.

/ˈlaŋli/, U.S.

/ˈlæŋli/

Etymology: < the name of Samuel P. Langley (1834–1906), U.S. astronomer. Originally proposed (in German) by F. Linke 1942, in Handbuch d. Geophysik VIII. 30, as a unit of solar energy flux, equal to one gramme-calorie per square centimetre per minute.

Meteorology.

A unit of solar energy per unit area, equal to one gramme-calorie per square centimetre (approximately 41,900 joules per square metre).

1947 Nature 6 Sept. 327/1 It is herewith proposed that the ‘langley’ be defined as the gm. cal./cm.², where ‘gm. cal.’ denotes the 15°C. gm. cal. It is also proposed that the written abbreviation of ‘langley’ be ‘ly’.

1954 J. C. Johnson Physical Meteorol. iv. 108 σ =..8·22 × 10⁻¹¹ langley minute⁻¹. σ is called the Stefan-Boltzmann constant.

1970 Day & Sternes Climate & Weather v. 145 The solar constant..is alternatively expressed as nearly 2·0 langleys per minute.

1974 Nature 15 Nov. 217/1 For the point of equilibrium I take 17 langley per day (1 langley = 1 calorie cm⁻²) above the 1950 value of 847 langley per day.
