LYNRED supplied three of the four critical detectors onboard the METOP-SG weather satellite, which was launched from Kuru, French Guyana, on Aug. 12, 2025. The satellite will orbit the Earth pole-to-pole to deliver near real-time data on the state of our atmosphere, resulting in more accurate forecasts, better disaster preparedness and a sharper view of the long-term effects of global warming. This program is another concrete demonstration of the potential of infrared technologies for atmosphere and climate observation. 

LYNRED’s infrared detectors are embedded in key instruments aboard the Metop-SG satellite: 

• Sentinel-5, which measures air quality and greenhouse gases like methane and carbon monoxide
• METImage, which monitors clouds, land surface, and temperatures
• 3MI, which analyzes atmospheric aerosols: fine particles that influence both climate and human health

These instruments provide critical insights for both climate scientists and public agencies. Data from Metop-SG will be used to issue storm warnings, track pollution episodes, monitor volcanic activity, and feed long-term climate models — ultimately helping governments, researchers, and citizens make informed decisions.
