High-resolution Adriatic ocean reanalysis fields previously came from bilinear interpolation or costly nested regional models, and interpolation smooths away fronts and mesoscale structure. OcDiffSR applies a conditional denoising diffusion probabilistic model to jointly super-resolve sea-surface temperature, salinity, and horizontal velocity, using 1/12° GLORYS12V1 fields as conditioning input to reconstruct 1/24° Med MFC fields. On the independent test year 2009, scalar-field errors fall well below interpolation and the residual diffusion model CorrDiff, with salinity RMSE of 0.346 psu and temperature RMSE of 0.477°C, while velocity correlation stays near 0.64.
