Benchmark scores

CSI / FAR / HR vs. each observation source, at every flood-fraction threshold.

Flood threshold

Minimum flooded fraction of a ~1 arcmin cell to count as "flooded", applied the same way to the model and all observations.

Layers

No interpolation (native pixels)

No model/observation layers available for this event.

Gray = no observation, VIIRS/MODIS (optical sensors blocked by cloud cover — irregular, can clear up on a later date). Genuinely unknown, not "confirmed not flooded" — excluded from that layer's CSI/FAR/HR scores.

Slate blue = no observation, GFM (radar sees through cloud, but the satellite swath doesn't cover this area — a fixed strip, not weather-related). Also excluded from scoring.

Hatched teal = known lake/river/reservoir (Reference water layer). This is a fixed geographic fact, not uncertainty — CaMa-Flood's flood fraction includes this extent, so it's excluded from scoring so it isn't counted as a false alarm.
