Anomaly map

Hexagons are real H3 cell boundaries. Colour scales with value; the legend states the resolution, because a res-5 cell is ~253 km² and a res-7 cell is ~5 km².

Daily fire detections

Iberia and Greece. Log axis by default — counts span four orders of magnitude.

Strongest departures

z is the departure from the region's own ±15-day seasonal baseline, in robust units (median and scaled MAD). The model percentile is shown where batch scoring has run.

Sea-ice extent

Latest value against the published NSIDC 1981–2010 per-day normal. The departure is sustained rather than episodic, so read the z-score rather than the flag.
