> "MTG-S1’s Infrared Sounder will scan nearly 2,000 thermal infrared wavelengths every 30 minutes to build vertical profiles of temperature, humidity, and trace gases. These data will be crucial for detecting fast-developing convective weather by revealing sudden shifts in instability, moisture, or wind – even before clouds begin to form."

In other words, it is

Is there a more technical article describing this hyperspectral instrument somewhere? It sounds pretty novel.

edit: Also, I'm now confused about the ESA's claim to be "the first", because

Imagine a world where America actually wanted to understand climate change.

Considering the emissions of the US and the outright rejection of climate action through the Paris accords, and the covering up of climate related research, it would seem fair to consider climate change as partly caused by outright American hostility. They say the most impacted will be people in developing nations, also, not in the US. Absolutely horrific actions.
