SSTA Standard Deviation – Spread of daily sea surface temperature anomalies. Higher values indicate more variable ocean temperatures.
SSTA Memory (τ) – Decorrelation timescale from lag-1 autocorrelation. Longer τ means anomalies persist for more days.
SSTA Trend – Linear trend in SST anomalies over 1982–2025. Positive = warming, negative = cooling (°C per decade).
SSTA Skewness – Asymmetry of the anomaly distribution. Positive skew means warm extremes are more intense than cold extremes.
Mean SST – Annual mean climatological SST from K=4 harmonic fit.
Min / Max Climatological SST – Coldest and warmest days in the seasonal cycle (harmonic reconstruction).
Seasonal Range – Difference between max and min climatological SST.
Day of Max / Min SST – Day of year when climatological SST peaks or reaches its minimum.

Controls
Rescale to View – Recomputes the color scale from the currently visible map extent. For trend and skewness, the scale is kept symmetric about zero.
Reset Scale – Returns to the default global color scale.
