A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting, or geostationary.
The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) is an intergovernmental organisation created through an international convention agreed by a current total of 30 European Member States.
The Meteosat series of satellites are geostationary meteorological satellites operated by EUMETSAT under the Meteosat Transition Programme (MTP) and the Meteosat Second Generation (MSG) program.
A scatterometer or diffusionmeter is a scientific instrument to measure the return of a beam of light or radar waves scattered by diffusion in a medium such as air. Diffusionmeters using visible light are found in airports or along roads to measure horizontal visibility. Radar scatterometers use radio or microwaves to determine the normalized radar cross section of a surface. They are often mounted on weather satellites to find wind speed and direction, and are used in industries to analyze the roughness of surfaces.
The advanced microwave sounding unit (AMSU) is a multi-channel microwave radiometer installed on meteorological satellites. The instrument examines several bands of microwave radiation from the atmosphere to perform atmospheric sounding of temperature and moisture levels.
Aeolus, or, in full, Atmospheric Dynamics Mission-Aeolus (ADM-Aeolus), was an Earth observation satellite operated by the European Space Agency (ESA). It was built by Airbus Defence and Space, launched on 22 August 2018, and re-entered the atmosphere over Antarctica in a controlled manner and burned up on 28 July 2023. ADM-Aeolus was the first satellite with equipment capable of performing global wind-component-profile observation and provided much-needed information to improve weather forecasting. Aeolus was the first satellite capable of observing what the winds are doing on Earth, from the surface of the planet and into the stratosphere 30 km high.

Upcoming missions that will deploy SCOS-2000 include MetOp-SG and EarthCARE.
Copernicus is the Earth observation component of the European Union Space Programme, managed by the European Commission and implemented in partnership with the EU Member States, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), the Joint Research Centre (JRC), the European Environment Agency (EEA), the European Maritime Safety Agency (EMSA), Frontex, SatCen and Mercator Océan.
Metop 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.
The Microwave Humidity Sounder (MHS) is a five-channel passive microwave radiometer, with channels from 89 to 190 GHz. It is very similar in design to the AMSU-B instrument, but some channel frequencies have been altered. It is used to study profiles of atmospheric water vapor and provide improved input data to the cloud-clearing algorithms in the IR and MW sounder suites. Instruments were launched on NOAA's POES satellite series starting with NOAA-18 launched in May 2005 and the European Space Agency's MetOp series starting with MetOp-A launched in October 2006 and continuing with MetOp-B launched in September 2012.
The Polar-orbiting Operational Environmental Satellite (POES), often confused with the South African slang term poes, is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting. The spacecraft were provided by NASA and the European Space Agency (ESA), and NASA's Goddard Space Flight Center oversaw the manufacture, integration and test of the NASA-provided TIROS satellites. The first polar-orbiting weather satellite launched as part of the POES constellation was the Television Infrared Observation Satellite-N (TIROS-N), which was launched on 13 October 1978. The final spacecraft, NOAA-19, was launched on 6 February 2009. The ESA-provided MetOp satellite operated by EUMETSAT utilize POES-heritage instruments for the purpose of data continuity. The Joint Polar Satellite System, which was launched on 18 November 2017, is the successor to the POES Program.
Sentinel-3 is an Earth observation heavy satellite series developed by the European Space Agency as part of the Copernicus Programme. It currently consists of 2 satellites: Sentinel-3A and Sentinel-3B. After initial commissioning, each satellite was handed over to EUMETSAT for the routine operations phase of the mission. Two recurrent satellites— Sentinel-3C and Sentinel-3D— will follow in approximately 2025 and 2028 respectively to ensure continuity of the Sentinel-3 mission.
The Earth and Mission Science Division is a group of European Space Agency (ESA) staff mission scientists, contractors, research fellows, young graduates, trainees, and administrative staff working within the Science, Applications and Climate Department of the Directorate of Earth Observation Programmes. The Division is located at ESA's European Space Research and Technology Centre in Noordwijk, South Holland, The Netherlands.
SEOSat-Ingenio, was a Spanish project to produce a satellite capable of providing wide-field imagery ensuring a repeat cycle of 38 days at 2.5 metre panchromatic resolution and 10 metre colour resolution, from a Sun-synchronous polar orbit; it was Spain's first optical imaging satellite. The satellite was part of the Spanish Earth Observation Satellite program. The mission was funded by Spain's Centre for the Development of Industrial Technology (CDTI). SEOSat-Ingenio information was to be used by various Spanish civil, institutional or government users. However, under the Copernicus Programme of the European Union, it was also accessible to other European users, as well as to the Group on Earth observation of the Global Observing System of Earth.
Ariane 6 is a European expendable launch system under development since the early 2010s by ArianeGroup on behalf of the European Space Agency (ESA). It replaces the Ariane 5, as part of the Ariane launch vehicle family. The stated motivation for Ariane 6 was to halve the cost compared to Ariane 5, and increase the capacity for the number of launches per year.
