Inter-comparison of Regional and Global Wave Reanalyses in the Mediterranean Sea, OSM26 presentation

This presentation discusses the inter-comparison of regional and global wave reanalysis products in the Mediterranean Sea using Copernicus Marine Service datasets. The analysis compares three operational systems (MED, IBI, and GLO) in overlapping regional domains and evaluates their consistency with in-situ buoy observations. The work presents initial results and methodological aspects of wave reanalysis validation, including considerations related to spectral differences between models and observations. This analysis contributes to ongoing international efforts within the Marine Environment Reanalysis Evaluation Project (MER-EP) aimed at improving the evaluation and intercomparison of ocean and wave reanalysis products. The presentation was delivered by Charikleia Oikonomou at the Ocean Sciences Meeting 2026 (OSM26) in Glasgow, UK, during the session “CC53A: Marine Environment Reanalyses and Four-Dimensional Data-Driven Models: Progress and Applications II” on 27 February 2026.
