Derived FireRadar dataset

What FireRadar has actually observed

This surface turns FireRadar's retained incident, status, size, and perimeter observations into measurable history. It reports the archive window beside the numbers so a partial-year FireRadar record can never be mistaken for a complete wildfire season.

Every statistic below is limited to this retained FireRadar window. For 2026, that means the archive begins after the season was already underway.

What these numbers do and do not mean

Per-fire maximum source-reported incident size observed by FireRadar; not cumulative hectares burned.

Migration baseline records help define what existed when FireRadar activated long-term history, but they are not counted as FireRadar first-seen events.

Status transitions and perimeter revisions are counted only when FireRadar retained an actual change event. Missing pre-FireRadar transitions remain unknown.
