Single models are everywhere
Single models are everywhere. This is the disagreement between them: per hour a median with a p15/p85 band, the full min/max spread, how many models still carry that hour, an agreement score, rain probability derived from pooled ensemble members rather than one deterministic run, a frost assessment, and the official DWD warnings in force for the point.
