The two OQOMETHI stations installed in April have been fitted with the current versions of the mFL-12 micro-fluorescence lidar and the mHR-2 micro-hyperspectral radiometer. Both instruments are integrated into autonomous micro-stations developed by vorteX-io for long-term operation with minimal intervention on site.
The passive mHR-2 and the active mFL-12 observe the same water body at the same time. The radiometer records reflectance, and the lidar records fluorescence from constituents such as chlorophyll-a and CDOM, so the two records are taken from the same water under the same conditions.
The complete systems have been in field testing since April 2026, operating unattended under natural conditions. The deployment is used to assess measurement performance together with reliability, remote operation, and data continuity over a period of months.
The work is carried out with vorteX-io and Magellium within OQOMETHI, supported by France 2030 and operated by ADEME.
