Twenty-Four Hours Above the Indian Ocean
High above the Indian ocean, a geo-stationary Russian weather satellite captures high-resolution photos of the planet. Videographer James Drake has put the images together into a series of time-lapse videos. Here are two of them.
Drake describes what you are seeing thus:
It creates a 121 megapixel image every 30 minutes with four visible and infrared light wavelengths. The infra-red was originally orange but I have changed it to green. The images are “masked” by a circular barrier that blocks out the light of the Sun and other stars. This is to prevent damage to the camera by exposure to direct sunlight. The images have been interpolated (blended) to create a smooth animation.
The second is a closer-up view of the northern hemisphere:
