Satellite Imagery

Satellite images provided on MetFlight GA come from a geostationary satellite orbiting the Earth over the equator at approximately 36,000 km.  Geostationary means it stays in the same position relative to the Earth, so is always looking at the same area.  The satellite measures emitted or reflected radiation from the Earth’s surface, clouds, precipitation, water vapour and other components of the atmosphere.  Modern satellites measure many different channels of the electromagnetic spectrum, but what we are interested in here are the visible (shorter wavelength) and infrared (longer wavelength) channels.
