Venice 2025, ESA PHY2FLEX field tests

First marine field tests of the full instrument suite, 7–9 October 2025, in the ESA PHY2FLEX campaign. LIFL-11, mFL-12, and mHR-2 ran three days in real sea conditions and returned clean data, with example Rrs spectra captured on 8 October. Vessel support provided by CNR (Italy).

In October 2025 LIFeLiDAR brought its full instrument suite to the Venice lagoon for the first marine field tests of the system, as part of the European Space Agency’s PHY2FLEX campaign. Over three days (7–9 October) the LIFL-11 multi-wavelength LIF LiDAR, the compact mFL-12, and the passive mHR-2 radiometer were operated together in real sea conditions, with vessel support from Italy’s Consiglio Nazionale delle Ricerche (CNR).

The campaign ran all three instruments through spray, vessel motion, and shifting light, and each returned clean data. The mHR-2 captured above-water remote-sensing reflectance (Rrs) spectra, the same quantity ocean-colour satellites estimate, with example spectra recorded on 8 October, while the active LIF sensors measured in-water constituents at the same place and time. Paired active and passive measurements of this kind are the building blocks of satellite cal/val match-ups.
