Meteosat series

Meteosat satellites are in geostationary orbit, so they orbit the Earth at the same rate that the Earth rotates about its axis. This enables continuous observations of around one-third of the Earth’s surface from their orbit 36,000km above the equator.

Observations from geostationary orbit can save lives on Earth, as changes in weather and climate significantly impact not only our economy and infrastructure but also our lives. According to the World Meteorological Organization, there were more than 11 000 disasters attributed to weather, climate and water-related hazards, which accounted for just over two million deaths and 3 trillion euros in losses between 1970 and 2019. Severe weather phenomena such as storms or even heavy fog can pose a significant threat to safety or business efficiency that require timely warnings to minimise their impact.

To issue warnings and support decision makers, weather forecasters perform “nowcasting” to detect, in real time, rapidly developing situations of high impact weather, and predict their evolution a few hours ahead.  Nowcasting requires very frequent, high-quality observational data about the state of the atmosphere in real time - data that advanced geostationary weather satellites such as Meteosat can deliver continuously from their fixed position above the Earth’s surface.

The Meteosat satellites are also able to deliver information on winds by observing the displacement of clouds and water vapour patterns; an essential input for numerical weather prediction models. These complement other observations made by polar-orbiting satellites such as Metop, which remain the primary source for global numerical weather prediction models.

Next generation satellites

The new generation of Meteosat satellites, Meteosat Third Generation (MTG) are Europe’s most advanced geostationary meteorological satellites. In addition to the Flexible Combined Imager instrument, they carry the Lightning Imager instrument, which will provide continuous, near-real time data that can be used to detect, monitor, and track lightning. Four cameras cover more than 86% of the Earth disc visible from the satellite and detect lightning including cloud-to-cloud, cloud-to-ground, and intracloud flashes.

This is the first time a geostationary weather satellite will have the capability to detect lightning data across a broad area over Europe, Africa, and the surrounding oceans. MTG will also provide observations of vertical temperature and humidity profiles at temporal and spatial scales previously unavailable. MTG satellites will ensure that Meteosat’s valuable contribution will continue into the 2040s.

Using MTG data

MTG data will provide a major boost to both nowcasting as well as short-range numerical weather prediction models.

Data collected by all Meteosat satellites is stored in EUMETSAT's long-term data preservation facility in Darmstadt, Germany. This includes essential information about clouds, solar radiation at the Earth’s surface, sunshine duration, precipitation, surface temperature, aerosols, wildfires, droughts, upper air winds, the life cycles of tropical storms, and much more.

The data are then used to create and maintain long-term climate data records together with the network of EUMETSAT Satellite Application Facilities. These long-terms records are, in turn, used in global reanalysis efforts (such as those undertaken by the European Centre for Medium-Range Weather Forecasts (ECMWF) as part of the Copernicus Climate Change Service) and further downstream in a variety of climate services.

The contribution of geostationary satellites towards climate monitoring is significant, with more than 40 years of Meteosat observations already accumulated. These data play a key role in important climate reports such as the Sixth Assessment Report in 2021 issued by the United Nation’s Intergovernmental Panel on Climate Change as well as the annual European State of the Climate compiled by the Copernicus Climate Change Service.

Meteosat satellites in orbit

EUMETSAT currently operates three satellites from the Meteosat Second Generation, Meteosat-9, -10 and -11 in geostationary orbit (36,000km) over Europe, Africa and part of the Indian Ocean. It also operates the first satellite of the Meteosat Third Generation series, MTG-I1, which was launched in December 2022.
