NettetAnswer (1 of 2): Cloud cover on the visible sky, also known as 'the celestial dome' is measured in octas: That is in eighths. If the whole sky is overcast with one type of cloud it would be eight eighths cloud cover. But each of any different type of cloud is estimated in the same way so an obser...

Serving as the WMO World Radiation Centre since 1971, it maintains the primary standard for measuring the Sun's irradiance, the so-called World Radiometric Reference. This ensures that these highly sensitive instruments, known …
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 how many eighths of the sky are covered in cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely overcast). In addition, in the SYNOP code there is an extra cloud cover indicator '9' indicatin…
NettetSensors are instruments that collect data about Earth processes or atmospheric components. Along with being carried aboard satellites or aircraft, sensors also can be installed on the ground (in situ). There are two types of sensors: active and passive. Active sensors provide their own source of energy to illuminate the objects they observe ... registering charityNettetSky conditions are estimated in terms of how many eighths of the sky are covered in cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely overcast). In addition, in the SYNOP code there is an extra cloud cover indicator ‘9’ indicating that the sky is totally obscured (i.e. hidden from view), usually due to dense … registering children as british citizensNettetnetworks, cloud macroscopic properties-mainly cloud cover, cloud depth, and cloud-base height-are still visually ob- served.
