How do I find my sky TV cover?
In meteorology, cloud cover is measured in oktas, or eighths of the sky. If you look up at the sky, and mentally divide it into eight boxes, then imagine all the cloud you can see squashed into these boxes. How many boxes does the cloud fill? This is how many oktas of cloud there are.
How do I check my cloud cover?
To measure cloud cover, you use oktas or eighths, which is the proper unit. If you want to do it at home, grab a mirror and divide it into eight squares. Place it correctly so you can see the clouds and count how many squares are covered by them.
What is Darksky?
Dark Sky is a short term weather predictor protoype for iOS devices (more about the developers efforts to turn this into an app at the end of this post). Dark Sky predicts the time and duration of weather at the local level within a window of 30-60 minutes into the future.
How satellites can be used to measure the amount and the height of clouds in the atmosphere?
Weather experts monitor clouds with the help of satellite data, and they use cloud height and motion data to calculate wind speed and height. Geostationary satellites measure reflected sunlight in only one direction for any given point on the surface or in the atmosphere.
How much of the sky is covered by clouds today?
One study based on nearly a decade of satellite data estimated that about 67 percent of Earth’s surface is typically covered by clouds. This is especially the case over the oceans, where other research shows less than 10 percent of the sky is completely clear of clouds at any one time.

Is Dark Sky accurate 2021?
Dark Sky is a weather app so good that Apple bought the company just to keep it exclusive to iOS starting August 1, 2020. Still, app’s slick presentation and hyper-local accuracy make it easy to see what all the fuss is about.
How much of the sky is hidden by clouds?
7 oktas represents a cloud amount of 7 eighths or more, but not full cloud cover. 8 oktas represents full cloud cover with no breaks. 9 oktas represents sky obscured by fog or other meteorological phenomena.
What instrument measures cloud cover?
Ceilometers
A ceilometer is a device that uses a laser or other light source to determine the height of a cloud ceiling or a cloud base from the ground. Ceilometers can also be used to measure the aerosol concentration within the atmosphere.
Why are there no clouds over the ocean?
Instead, researchers found that, as oceans become warmer, low-level clouds dissipate from the skies. This means more sunlight reaches the ocean surface – a runaway process that leads to more warming and less cloud cover.
