Noun
okta (plural oktas or okta)
- (meteorology) One eighth of the total area of the celestial dome; used as a measure of cloudiness (one okta means that one eighth of the sky is obscured, two oktas that one quarter is obscured, and so on).
- 1960, American Meteorological Society, Meteorological and Geoastrophysical Abstracts, American Meteorological Society, Page 480
- ...64% of the low- and 50% of the high-cloud amount differences were within ± 1 okta, although many of these successes (71% in the low-cloud amount) were for cases of totally clear or totally cloudy skies.
- 1977, John Le Carré, The Honourable Schoolboy, Folio Society 2010, p. 426:
- ‘Fog is traditional for the season and cloud is anticipated at six to seven oktas, sir.’
- 1985, University of East Anglia, Geo Abstracts, University of East Anglia, Page 29
- Mean cloud amount distributions are transformed to normal distributions. The accuracy of the method is indicated by the retrieval of the original distribution with a typical error of 14% in the frequency of each okta of cloud amount.
- 2001, W.G. Rees, Physical Principles of Remote Sensing - Second Edition, Cambridge University Press, Page 100
- For example, it has been estimated that a Landsat satellite, which revisits a particular location once every 16 days, will obtain a cloud-free scene of a particular location in Britain only once per year, and a scene with 1 okta of cloud (an okta is one eighth of the sky obscured by cloud) only twice per year.
