Minimize MetOp Programme
Web Content Image

The Meteorological Operational satellite programme (MetOp) is a European undertaking providing weather data services that are used to monitor climate and improve weather forecasts. The MetOp programme's series of three satellites has been jointly established by ESA and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), forming the space segment of EUMETSAT's Polar System (EPS).

The programme also represents the European contribution to a new cooperative venture with the United States' National Oceanic and Atmospheric Administration (NOAA), which for the last 40 years has been delivering meteorological data from polar orbit, free of charge, to users worldwide.

With an array of sophisticated instrumentation, MetOp satellites can provide data of unprecedented accuracy and resolution on a host of different variables such as temperature and humidity, ocean surface wind speed and direction and concentrations of ozone and other trace gases - thus marking a major advance in global weather forecasting and climate monitoring capabilities.
