With its array of advanced instruments, it will provide data of unprecedented accuracy and resolution on temperature and humidity, wind speed and direction over the ocean, and ozone and other trace gases, making a huge contribution to global weather forecasting and climate monitoring. In addition, MetOp-A will observe land and ocean surfaces and its search-and- rescue service will help ships and aircraft in distress. Introduction MetOp-A is Europe’s first satellite dedicated to operational meteorology from polar orbit. It will balance the long-standing service provided by the US since the first Tiros satellite in 1960. The US has provided the data from this evolving series free of charge to the world’s meteorological community. As early as
