sky coverage

Sky coverage refers to the extent of the sky that is visible or observable from a specific location, often in relation to astronomy, weather, or satellite monitoring. It describes how much of the sky can be seen at a given time, considering obstacles like buildings, trees, or atmospheric conditions. For example, an observatory might have 80% sky coverage, meaning it can see 80% of the sky above its horizon, while the remaining 20% is blocked or obscured. It helps assess how well a site or instrument can observe celestial objects or track phenomena across the sky.
