MTG-I2 in the gantry

MTG-I2 is part of the MTG constellation for Eumetsat – two are already in orbit – and it will produce images for weather forecasting in Europe in unprecedented detail. This mission provides completely new data products and capabilities for European weather services, especially suited to nowcasting of severe weather events.

The MTG-Imager satellites carry two instruments, a Lightning Imager and a Flexible Combined Imager. The Lightning Imager offers completely new capabilities for European meteorological satellites by continuously monitoring for lightning. By doing this from geostationary orbit, at an altitude of about 36 000 km above the equator, it can scan more than 80% of Earth’s surface seen from that viewpoint.

The Flexible Combined Imager, on the other hand, builds a picture of fast-evolving weather systems and can be used to issue timely weather warnings. It is particularly relevant for air traffic safety. It is able to scan its view of Earth in just 10 minutes and can scan Europe and northern Africa every 2.5 minutes.

When MTG is fully operational, it is expected to produce at least 50 times more data than the previous Meteosat Second Generation (MSG) satellites.
