Processed multisensor dataset and derived analysis tables for the Samothraki anticyclonic circulation and thermal-front system in the northeastern Aegean Sea, 2018–2021

This dataset contains processed multisensor satellite-derived data, derived daily and regional metrics, statistical tables, classification outputs, and supporting analysis material used for the manuscript on the Samothraki anticyclonic circulation and associated thermal-front system in the northeastern Aegean Sea during 2018–2021.The archive includes quality-controlled Sentinel-3 SLSTR sea surface temperature derived metrics, AVISO/CMEMS sea-level and geostrophic-current diagnostics, sea-surface salinity context, wind data summaries, Sentinel-3 OLCI ocean-colour derived metrics, regional ROI-based tables, statistical outputs, and figure-supporting data required to reproduce the main analyses reported in the manuscript.The original satellite products are not redistributed in this archive. They remain available from the respective Copernicus, CMEMS, EUMETSAT, and AVISO data services, subject to their original terms of use.
