Annual Raster Dataset of Empirically Derived Key SST Phenology Metrics for the Mediterranean Sea (1982–2024)

This dataset contains annual raster files representing key sea surface temperature (SST) phenology metrics and threshold-based outputs for the Mediterranean Sea over the period 1982–2024. The metrics are organized into separate folders according to their names, and the dataset includes 43 yearly rasters describing the fundamental seasonal characteristics of the SST cycle, together with threshold values computed using the three possible index formulations. This structured organization facilitates access to individual metrics and supports analyses of interannual variability, long-term change, and seasonal thermal dynamics at basin scale. The SST phenology metrics are calculated by empirically-based method described in Thomas et al. (2017): Start of Season — SOS, t_SOS or onset, End of Season — EOS or t_EOS, Season Length — Duration or duree, SST at SOS time — SST_SOS, SST at EOS time — SST_EOS, Cumulated heat — heatcum, Mid season Value — Mid_season.
