WM‑5c valid time
For WM‑5c, the valid time of a forecast is forecast_zero + forecast_hour , NOT initialization_time + forecast_hour .
WM‑5c runs every 20 minutes (initialization_time), but valid times stay on a fixed 3‑hourly cycle (forecast_zero). Multiple runs can share the same forecast_zero as later runs assimilate newer observations while keeping valid times stable.
Alternatively, you can use the time or valid_at (NetCDF/ZARR) parameter to request or use forecast data by valid time directly.
See Time in Forecasts for full details.
