Do you know the role of partners in HALLOA? To meet the stringent laser source requirements, the HALLOA project is developing a so-called hybrid laser architecture that synergistically combines the benefits of fiber-based systems with the capabilities of free-space designs: Fiber amplifier: excellent optical properties, alignment-free and versatility Free-space amplifier: high power and with lower […]

Document overview The context of the present technical development is the continuous increase of CO₂ concentration in the atmosphere and the perturbation of global Earth carbon cycle.  The land sink study is definitively the main interest of the development of CO₂ lidar measurements ultimately from space. One must understand here that CO₂ surface flux and […]

From pioneering wind profiles to monitoring greenhouse gases: Europe’s leadership in space-borne LiDAR is a journey of precision 💡How did we get here? Before HALLOA, several landmark missions paved the way for active sensing from space: Aeolus (2018-2023): The pioneer that proved LiDAR works in orbit from EarthCARE (since 2024): Deepening our understanding on clouds […]

Article from HALLOA’s partner LZH Orginal article available here Researchers at LZH are developing a robust laser system for monitoring greenhouse gases from space using a hybrid approach as part of the EU project HALLOA. The goal is to provide precise data to improve our understanding of the climate, while also strengthening Europe’s technological independence. […]

Discover the LIDAR developed by HALLOA european project HALLOA is a consortium project bringing together 6 partners in response to a European call for tenders on the theme of ‘Space technologies at the service of Europe’s non-dependence and competitiveness’.   HALLOA is a research and development project aimed at developing a streamlined and robust laser system […]

On 16 September 2025, the HALLOA partners met in Brussels, Belgium for the project’s first Review with the Project Officer and external experts.

The HALLOA project (Hybrid Amplifier Laser for Lidar OperAtions) has officially launched in January 2025 under Horizon Europe, with the mission to advance European space technologies for greenhouse gas monitoring.
