Cloud cover such as the Amazon Rainforest and some others are almost always clear such as the Sahara Desert. Cloud cover Cloud cover (also known as cloudiness, cloudage, or cloud amount) refers to the fraction of the sky obscured by clouds when observed from a particular location. Okta is the usual unit of measurement of the cloud cover. The cloud cover is correlated to the sunshine duration as the least cloudy locales are the sunniest ones while the cloudiest areas are the least sunny places. The global cloud cover averages around 0.68 when analyzing clouds with optical depth larger than 0.1. This
Unit of measurement is just mathematically the same thing, multiply "Z" by unity, the product is still "Z": For example, you have an expression for a physical value "Z" involving the unit "feet per second" (formula_9) and you want it in terms of the unit "miles per hour" (formula_10): Or as an example using the metric system, you have a value of fuel economy in the unit "litres per 100 kilometres" and you want it in terms of the unit "microlitres per metre": One example of the importance of agreed units is the failure of the NASA Mars Climate Orbiter, which was accidentally
