From 7 to 9 October 2025, LIFeLiDAR operated the LIFL-11, mFL-12, and mHR-2 together in the Venetian Lagoon. The work formed part of the European Space Agency’s PHY2FLEX campaign, with vessel support from Italy’s Consiglio Nazionale delle Ricerche.

The three-day programme provided the first joint marine test of the current instrument suite under spray, vessel motion, and changing natural light. On 8 October, the mHR-2 recorded above-water Rrs while the active LIF instruments measured fluorescence in the same water. These synchronous observations form the paired record used in satellite cal/val.
