Rainfall frequency grids

1km Rainfall Depth-Duration-Frequency Grids: Each grid gives point rainfall depth estimates in mm for a specified duration (hours) and return period (years). Grids are derived from the six-parameter FEH rainfall depth-duration-frequency (DDF) model as described in the Flood Estimation Handbook Volume 2.Rainfall grids
