WRF Precipitation Verification
loading…
How to read this. Every completed WRF run is compared against INAMHI
hourly rain gauges inside the 3 km nest. Pick an accumulation window and a
matching rule below — the matching rule matters more than any single score.
Scoring starts at forecast hour 1; an N-hour accumulation cannot be closed
before hour N, so the 24 h window necessarily begins at f24. The lead axis
is binned in 6-hour groups.
