First UV lidar deployed to Observatoire de Haute‑Provence

The first UV lidar developed in EULIAA has been successfully deployed to the Observatoire de Haute‑Provence (OHP) in Southern France.
After only a few weeks of test runs at IAP, the system was transported by truck and achieved first atmospheric measurements on the evening of arrival—without any realignment—demonstrating excellent robustness.
The UV lidar now provides continuous measurements up to about 100 km altitude, including the iron layer around 80 km, operating autonomously (weather permitting) and showcasing new solutions for full‑daylight capability; Altechna contributed high‑damage‑resistance UV optics and filters and advanced telescope optics to this milestone.
