Every day remote sensing satellites fly high overhead taking images of the land and sea. Remotely sensed images may be combined with graphics. By manipulating color and animating the images, complex environmental phenomena can be revealed. Remotely sensed imagery provides a view of the earth from space. Scientists can actually watch a weather system as it passes over a large section of the globe and can predict with good accuracy when locations in the system's pathway will be hit.
Satellites take many pictures.
Most satellite images have the time written on them, but it is in a form that may be difficult to read. Here is a guide to finding the time. As you know, there are many different time zones around the globe. All three refer to the time in London along the Greenwich Meridian. You can use a chart to convert a U.T., Z, or GMT time to the zone where you live.
