The following “decision-ready” products are derived from the full time series of flood susceptibility maps from 2000 to 2023. Each layer provides an easy-to-understand summary of long-term patterns, current conditions, or year-to-year variability.

- Extreme Wet and Dry Years (GEV Analysis): Identifies the years with unusually high and unusually low flood‑related conditions, along with the average flood susceptibility during those years. Helps users understand how extreme conditions shape long‑term patterns. Values range: 0 to 100

- Flood Susceptibility Envelope: Combines the extreme wet and extreme dry years to show the full range of possible flood susceptibility values for each location. Pixel Values: 0 = Non-flooded, 1 = Dry extreme years, 2 = Wet extreme years (higher probability of wet conditions), 3= Wet extreme years with low confidence

- Trend Slope (2000–2023): Examines each pixel over the full time span and calculates whether susceptibility is increasing or decreasing. Values above 1000 indicate increasing susceptibility and values below 1000 indicate decreasing susceptibility.

- Trend Class: Groups pixels into classes based on how consistently they show wet‑year or dry‑year behaviour over time. Helps highlight areas with clear long‑term patterns. Pixel values: 6=Strong Wetting, 5=Moderate Wetting, 4=Inconclusive, 3=Mixed Significant, 2=Moderate Drying, 1=Strong Drying, 255=NoData.

- Current Flood Susceptibility: Shows the estimated average conditions for the most recent period—useful for understanding how things look today. Values range: 0 to 100

- Current Interquartile Range (IQR): Measures how much flood susceptibility varies from year to year under current conditions. Higher values indicate locations with more variability. Coloured by range: 0 - 4 = Very stable, 5 - 9 = Light Interannual Variability, 5 - 9 = Moderate Interannual Variability, 10-19 = Strong Interannual Variability, 20-29 = Very Strong Interannual Variability, 30-52 = High instability
