First View of Aerosols from MetOp-SG’s 3MI InstrumentMetOp Second Generation (MetOp-SG) was launched in August 2025. Two of its instruments have already returned first data. Now it’s the turn of the Multiviewing multichannel multipolarisation imager (3MI), which was built by Leonardo and provides data on aerosols in our atmosphere. The first images captured by 3MI are a view over Northern Africa, Italy and the eastern Mediterranean,
