Danube model-cell comparison

The selected model-cell discharge is compared with lower-tail percentile boundaries for the same calendar month, derived from that cell's stored GloFAS climatology. P10 and P20 determine the label; the median only positions the bar.

Formulabelow model P10 if Q < model P10; model P10-P20 if model P10 ≤ Q < model P20; at or above model P20 if Q ≥ model P20

Data & provenanceGloFAS v4 via Open-Meteo · stored climatology for the selected model cell

LimitThe model value for this day is compared with this exact cell’s stored monthly GloFAS v4 climatology. Below P10, P10-P20, and at or above P20 are European model-comparison bands. P10 means the 10th percentile of that model record; it is not Q355, Q364, or a statutory minimum residual flow.
