Visible imagery from satellites is only available during which time?

Visible imagery from satellites is primarily available during daylight because this type of imagery relies on sunlight for capturing images of the Earth's surface. Visible light is a portion of the electromagnetic spectrum that human eyes can detect, and for satellites to capture clear and detailed images, sunlight must illuminate the areas being observed.

At night, visible imagery is not possible because there is no natural light for the satellite sensors to detect. During cloudy weather, clouds obstruct the view of the surface, making it difficult or impossible to obtain clear images. Similarly, while it is raining, precipitation can obscure visibility, and the effects of raindrops can distort the acquired images. Therefore, daylight is essential for obtaining usable visible imagery from satellites.
