A series of three polar-orbiting meteorological satellites developed by the European Space Agency (ESA), Eumetsat, NOAA, and the French space agency (CNES), and forming the space segment of the Eumetsat Polar System (EPS). MetOp-1 was launched on 19 October 2006 and became fully operational by 15 May 2007. The satellites will eventually become the morning series of a NOAA-Eumetsat system that will replace the ageing NOAA (2) series. MetOp satellites (orbiting at an altitude of c.800 km) will continue some of the monitoring carried out by the European Remote Sensing Satellites and will also complement the observations made by Envisat. Apart from a newly developed suite of sophisticated instruments (see Advanced Scatterometer; Global Ozone Monitoring Experiment; GNSS Receiver for Atmospheric Sounding; Infrared Atmospheric Scanning Interferometer; and Microwave Humidity Scanner) they carry legacy instruments identical to those used on NOAA polar-orbiting satellites (see Advanced Microwave Sounding Unit; Advanced Very High Resolution Radiometer; and High Resolution Infrared Sounder) to ensure compatibility and continuity between datasets obtained with different instruments.
