The paper describes a comprehensive field experiment conducted from a stationary hydrophysical platform in the Black Sea near the town of Katsiveli, Republic of Crimea, at the Marine Research and Technology Shared Use Center of Marine Hydrophysical Institute RAS. The equipment used in the experiment included a radiometric system consisting of two 8-mm-band radiometer-polarimeters. The radiometers were mounted on a Traverse-2 rotating scanning platform. Laser wave recorders were used in the experiment and are still in operation, monitoring sea wave parameters. Laser measurements utilize a scanner that allows the laser beam to be swept along a specified trajectory at the same frequency as a video camera. The image in the video camera is updated at each frame. The scanner stops at specified points along the trajectory allowing for images of the beam boundaries to be obtained with a higher signal-to-noise ratio and measurements to be conducted even in daylight. The measurements also utilize three continuous lasers, which form three points on the sea surface at a specified distance. This allows for measuring not only sea surface elevation over time at specified points but also obtaining a two-dimensional slope distribution and determining the wave frequency spectrum. Experimental studies of the relationship between surface wind and the dynamics of wind wave development on the sea surface were based on synchronous wind field measurements using two sonic anemometers of the MK-15 meteorological complexes, installed on an offshore platform at specified elevation levels. During the experiment in the summer of 2025, unique measurements of wind field, sea waves, and polarization characteristics of sea surface emission were obtained under various meteorological conditions. The data obtained will enable research into the interaction of polarized microwave radiation at the sea surface – atmosphere interface, considering the relationship between wind in the atmospheric surface layer and sea wave structure.
