LEMON DIAL mechanical integration

In the past few months, some key technical milestones were achieved: the LEMON receiver integration was completed end of 2022, whereas the emitter mechanical integration took place in January 2023. The LEMON consortium is thus pleased to announce that the mechanical integration of the LEMON Differential Absorption Lidar is completed.

New challenges now wait for us until the project end in June 2023, i.e., the overall instrument optical alignment, the remote control and DIAL tests, and the final airborne demonstration phase onboard the Safire ATR-42.

Some key project results will be presented at the LEMON Final Public Workshop, that will take place online mid of July 2023. Stay tuned for more information on the event date and agenda.
