Europe’s latest weather satellite, Meteosat 3G Imager, delivers first Earth views

05 May 2023

More detailed images are “great example of European cooperation”, says European Space Agency.

Europe’s latest weather satellite, the Meteosat Third Generation Imager, has just delivered its first view of Earth – revealing conditions over Europe, Africa and the Atlantic in remarkable detail.

Launched on an Ariane 5 rocket on 13 December 2022, the Meteosat Third Generation Imager-1 (MTG-I1) is the first of a new generation of satellites set to revolutionise weather forecasting in Europe. European Space Agency (ESA) and Eumetsat are proud to jointly release the new image from the next generation.

ESA’s Director of Earth Observation Programmes, Simonetta Cheli, said, “This image is a great example of what European cooperation in space can achieve. The level of detail MTG-I1’s image reveals, unachievable over Europe and Africa from a geostationary orbit until now, will give us a greater understanding of our planet and the weather systems that shape it.

“This image represents not just what can be achieved through European expertise but our determination to ensure the benefits of new technology are felt by communities in Europe and beyond.”

Instruments onboard the third generation of Meteosat meteorological satellites produce imagery with a much higher resolution, and more frequently, than those on the Meteosat Second Generation satellites.

More detailed

Details such as cloud vortices over the Canary Islands, snow cover on the Alps and sediment in the water along the coast of Italy are visible in the image. These details are not as clearly visible, or not visible at all, in images from the instruments on the current second-generation spacecraft.

The new imaging capability also reveals a greater level of detail of cloud structures at high latitudes. This will enable weather forecasts to monitor the evolution of rapidly developing severe weather more accurately in that region.

Phil Evans, Director General at Eumetsat, said, “This remarkable image gives us great confidence in our expectation that the MTG system will herald a new era in the forecasting of severe weather events.

“It might sound odd to be so excited about a cloudy day in most of Europe. But the level of detail seen for the clouds in this image is extraordinarily important to weather forecasters. That additional detail from the higher resolution imagery, coupled with the fact that images will be produced more frequently, means forecasters will be able to more accurately and rapidly detect and predict severe weather events.”

Natalia Donoho, Head of the World Meteorological Organization Space Systems and Utilization Division, WMO, said, “The high-resolution and frequent repeat cycle of the Flexible Combined Imager will greatly help the World Meteorological Organization community to improve forecasts of severe weather, long-term climate monitoring, marine applications, agricultural meteorology, and will make an important contribution to the Early Warnings For All Initiative, in particular on the African continent.”

‘Commissioning phase’

MTG-I1 is currently undergoing a 12-month commissioning phase, in which its instruments, the Flexible Combined Imager and the Lightning Imager, are switched on and the data they produce are calibrated. Data from the satellite will then be disseminated to meteorological services in Europe and beyond at the end of 2023, for operational use in weather forecasts.

The ground segment infrastructure required to routinely process images was used to produce this first image, as a preview of things to come this year. Images of the full Earth disc will be produced every 10 minutes when the system is fully operational.

The MTG satellites are built by a large consortium of European industries, led by Thales Alenia Space in cooperation with OHB. The innovative Lightning Imager was developed by Leonardo in Italy, while Telespazio provides Eumetsat with launch and in-orbit services.
