MTG‑I2 Ready for Launch: New Meteosat Generation Aims to Improve Severe‑Weather Early Detection

Another satellite pair of the Meteosat Third Generation is being deployed: MTG‑I2 is set to launch from French Guiana aboard an Ariane 6 rocket and will provide Europe with much finer weather imagery — particularly relevant for short‑term forecasts of severe storms.

Ahead of the night launch on 27 August 2026, the Meteosat Third Generation Imager 2 (MTG‑I2) is standing by at the European spaceport in French Guiana. Aboard an Ariane 6 launcher, the satellite will lift off at 22:10 CEST (17:10 local time) and will augment the MTG satellites already in orbit. The aim of the mission is to supply weather services across Europe with much more detailed and faster image data, with particular focus on the early detection of severe storms.

Why a new Meteosat matters

Meteosat satellites provide continuous observations of Europe from geostationary orbit. This fixed position relative to Earth's surface allows uninterrupted monitoring of cloud development and atmospheric processes. MTG‑I2 belongs to the third generation of this satellite family and brings new measurement capabilities and data products compared with older systems. For meteorological services this means, concretely: more precise information on the formation and evolution of convective cells, faster image sequences to observe rapidly developing storms, and an improved basis for nowcasting models that create short‑term warnings.

What MTG‑I2 delivers

The satellite focuses on optical and infrared imagery available at an unprecedented level of detail. This high resolution increases the detectability of small but dangerous cloud structures that often precede heavy rain, hail or strong gusts. In addition, new combined data products will be produced, showing, for example, temperature profiles in cloud layers or rapid changes in cloud formation. Such information helps weather services issue severe‑weather warnings with higher accuracy and longer lead times.

Significance for short‑term forecasts

In weather situations with strong convection, minute‑to‑hour precision determines the quality of a warning. MTG‑I2 offers image sequences with higher temporal resolution, allowing meteorologists to follow developments almost in real time. That increases the chance to react quickly to local hazards such as suddenly onset heavy rainfall. For disaster management, municipalities and emergency services, the improved basis for operations and precautionary measures — for example closing vulnerable road sections or targeted evacuations — is crucial.

Launch site and mission integration

The launch will take place from the European spaceport in French Guiana. The chosen launcher, Ariane 6, the latest generation of European launch vehicles, regularly performs key tasks supplying geostationary and low Earth orbits. MTG‑I2 will complement the existing MTG constellation, which has been built up step by step in recent years to secure Europe’s long‑term observational capabilities.

Technology and cooperation

The MTG missions are the result of cooperation between European space and meteorological agencies. EUMETSAT coordinates the operational management of the Meteosat fleet and distributes the collected data to national weather services and research institutions. Onboard the satellites are instruments specifically designed for weather observation needs: broad spectral bands to distinguish cloud and surface types, rapid image sequences to capture dynamic processes, and product generation that feeds directly into forecasting models.

What matters after launch

Immediately after satellite deployment a series of tests and commissioning phases will follow. Orbit adjustments, attitude checks and instrument calibration will take several weeks. Only after successful completion of these checks will MTG‑I2 deliver routine data to the weather services. In its operational phase the satellite will provide routine monitoring and also offer the possibility to activate special observation modes when extreme weather situations are expected.

Impacts for climate research and society

The improvement of the short‑term warning chain is primarily a meteorological benefit, while climate and environmental research also profit. Long‑term collections of high‑resolution satellite data allow finer analyses of trends in extreme precipitation and storm events — important building blocks for adaptation strategies to a changing climate. At the local level, higher warning quality and forecast reliability directly contribute to reducing property damage and risks to people.

Outlook

With the launch of MTG‑I2, Europe’s operational Earth‑observation capacity will grow. The combination of improved image quality, faster updates and new product functions strengthens the ability to detect severe weather earlier and to inform affected regions more effectively. After the commissioning phase, meteorologists across Europe will have extended tools at their disposal that can help determine outcomes in critical situations for lives and property.
