The Franco-German satellite MERLIN is due to be launched into space in 2025 to measure the methane concentration in the Earth's atmosphere - a milestone in climate research. Important components of the LiDAR measurement system come from the Ferdinand-Braun-Institut in Berlin, which has now delivered the required laser diode benches to the project partner. The MERLIN mission aims to better understand the effect of the greenhouse gas methane on global warming. A radar-like laser system on the satellite measures natural and anthropogenic methane emissions: The...
