What is the sky cover of a layer of smoke aloft that covers 8/8 of the sky?

The sky cover of a layer of smoke aloft that covers 8/8 of the sky indicates a complete and uniform coverage. In aviation weather observations, sky cover is typically reported in eighths, which measure the amount of the sky obscured by cloud or other meteorological phenomena.

When smoke covers the entire sky, it is classified as 8/8, which means that 8 sections out of a total of 8 are filled. This designation communicates that there is no visible clear sky, and conditions are completely obscured by the smoke layer.

The other options do not accurately represent a complete coverage. For instance, selections that suggest fewer than 8/8 imply that some part of the sky remains clear, which is not the case here. A measurement like 9 eighths is not possible, as there cannot be more than total coverage in the context of sky observations. Thus, the correct characterization of the smoke covering the entire sky is indeed reflected by the answer of 8 eighths.
