Cloud cover factor
Cloud cover (also known as cloudiness, cloudage, or cloud amount) refers to the fraction of the sky obscured by clouds on average when observed from a particular location. Okta is the usual unit for measurement of the cloud cover. The cloud cover is correlated to the sunshine duration as the least cloudy locales … See more Clouds play multiple critical roles in the climate system and diurnal cycle. In particular, being bright objects in the visible part of the solar spectrum, they efficiently reflect light to space and thus contribute to the … See more Cloud cover values only vary by 0.03 from year to year averages, whereas the local, day to day variability in cloud amount typically rises to 0.3 … See more • NSDL.arm.gov, Glossary of Atmospheric Terms, From the National Science Digital Library's Atmospheric Visualization Collection. • Earthobersvatory.nasa.gov, Monthly maps of global cloud cover from NASA's Earth Observatory See more Although clouds can exist within a wide range of altitudes, typical cloud cover has a base at approximately 4,000m and extends up to an altitude of about 5,000m. Clouds height can vary depending on latitude; with cloud cover in polar latitudes being slightly lower … See more WebCloud factor F cl (all-sky divided by clear-sky incoming longwave radiation) versus the effective cloud-cover fraction n eff derived from the solar radiation model (Equation (1)) between 1100 and 1500 h LT (N = 2800 hours) at AWS3 on Kilimanjaro.
