The Infrared Sounder (IRS) on the MTG-S satellite represents the first hyperspectral imaging Fourier Transform Spectrometer operating from geostationary orbit. By providing high-resolution thermal infrared data with a 30-minute revisit time, the instrument dramatically enhances the detection of extreme weather phenomena. Its capability to record nearly 2000 channels enables transformative improvements in numerical weather prediction and climate research.
