C3S multi-system · drag to pan · scroll to zoom
Drag a map to pan and scroll over it to zoom (or use the sliders). The view syncs across all skill maps and, separately, across all forecast maps — skill and forecast move independently. Pick the forecast region above.
Provider skill — correlation
Higher correlation = more skill. Set each provider good/ok/bad — the grouping below updates live. Drag/zoom any skill map to reframe them all.
Forecasts grouped by skill
One row per skill level, plus the providers you haven't classified yet. These follow the forecast pan/zoom set above.
Advanced — forecast product & sources
Forecast product
Skill maps are global PNGs from the C3S verification gallery; forecasts are the selected region's continent embed (e.g. Africa = area11). Pan/zoom is a CSS transform applied live to every map of that type — drag or scroll any one and the rest follow.
