Okta to traditional approaches, satellite images do not account for cloud composition. Oktas are often referenced in aviation weather forecasts and low level forecasts: SKC = Sky clear (0 oktas); FEW = Few (1 to 2 oktas); SCT = Scattered (3 to 4 oktas); BKN = Broken (5 to 7 oktas); OVC = Overcast (8 oktas); NSC = nil significant cloud; CAVOK = ceiling and visibility okay. Okta In meteorology, an okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station. Sky conditions are estimated in terms of
Theory of conjoint measurement to some kind of unit difference. Each level of "P" is a difference between the levels of "A" and "X". However, it is not clear from the literature as to how a unit could be defined within an additive conjoint context. proposed a scaling method for conjoint structures but he also did not discuss the unit. The theory of conjoint measurement, however, is not restricted to the quantification of differences. If each level of "P" is a product of a level of "A" and a level of "X", then "P" is another different quantity whose measurement is expressed as a
