← California Fire Watch

Model lab

How well the "fire signal" on unconfirmed satellite heat predicts reported fires. Every hotspot in California is tracked from its first satellite pass, scored as data arrives, and later matched against CAL FIRE and NIFC incident reports. Research only.

Scorecard

New hotspots only (tracks that started on an already-reported fire are left out). A track is resolved once it's matched to a reported fire, or after 72 hours without new heat.

New hotspots per day

Pacific time, by first satellite pass. Bar color is the strongest signal the track reached.
