IAGOS-CARIBIC is operational again! The first interesting flight sequences Munich – Seoul – Munich and Munich – Capetown – Munich took place from 11. to 13. December 2017. It was more than 20 month of real hard work to rebuild the container, implement new and revised instruments and certify this new improved revision of the flying IAGOS-CARIBIC laboratory. We want to thank all involved partners and persons: Lufthansa Environmental Concepts, Lufthansa Technics, enviscope and all our colleagues from other institutes for their support, help and patience.
