The Cloud Layer

Five weather satellites hang over the equator, each watching its side of the planet and looking again every ten minutes. Their views are joined into one sky on a globe you can turn, zoom and play back over the last days. The land is this week's clearest look from the same satellites; the light, the stars and the Moon follow the moment shown. With gratitude to NOAA, JAXA, EUMETSAT and NASA, who build, fly and share these instruments.
