Designed to operate in geostationary orbit above the Earth, the GOES spacecraft continuously view the continental United States, the Pacific and Atlantic Oceans, Central America, South America, and southern Canada. The three-axis, body-stabilized design enables the sensors to "stare" at the Earth and thus more frequently image clouds, monitor the Earth's surface temperature and water vapour fields, and sound the atmosphere for its vertical thermal and vapor structures. The evolution of atmospheric phenomena can be followed, ensuring real-time coverage of meteorological events such as severe local storms and tropical cyclones. The importance of this capability was proven during hurricanes Hugo (1989) and Andrew (1992).
