Concept
MetOp
Summary
Metop (Meteorological Operational satellite) is a series of three polar-orbiting meteorological satellites developed by the European Space Agency (ESA) and operated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The satellites form the space segment component of the overall EUMETSAT Polar System (EPS), which in turn is the European half of the EUMETSAT / NOAA Initial Joint Polar System (IJPS). The satellites carry a payload comprising 11 scientific instruments and two which support Cospas-Sarsat Search and Rescue services. In order to provide data continuity between Metop and NOAA Polar Operational Environmental Satellites (POES), several instruments are carried on both fleets of satellites.
Metop-A, launched on 19 October 2006, is Europe's first polar orbiting satellite used for operational meteorology. With respect to its primary mission of providing data for Numerical Weather Prediction, studies have shown that Metop-A data are measured as having the largest impact of any individual satellite platform on reducing 24-hour forecasting errors, and accounts for about 25% of the total impact on global forecast error reduction across all data sources.
Each of the three satellites were originally intended to be operated sequentially, however good performance of the Metop-A and Metop-B satellites mean there was a period of all three satellite operating. EUMETSAT lowered the orbit of Metop-A and decommissioned the spacecraft in November 2021
The successor to the Metop satellites will be MetOp-SG, currently with the first MetOp SG-A satellite expected to be launched in 2025.
The following instruments are flown on board the Metop satellites:
The following instruments are shared on the NPOES satellites which form the U.S. contribution to IJPS:
AMSU-A1/AMSU-A2 – Advanced Microwave Sounding Units
HIRS/4 – High-resolution Infrared Radiation Sounder (N.B. Not included on Metop-C)
AVHRR/3 – Advanced Very High Resolution Radiometer
Argos A-DCS – Advanced Data Collection System
SEM-2 – Space Environment Monitor
SARP-3 – Search And Rescue Processor (N.
