Kahu Ola SmokeWatch

Wildfire watch for Hawaiʻi from GOES-18, every 5 minutes. An AI agent gathers the evidence; a human decides what is published.

Case study · replay of real satellite data

Lahaina, Maui — 8 Aug 2023

Times in HST (UTC−10) and UTC. “Report” is the first official report, not when people first noticed the fire.

GOES-18 true color over Maui, 12:00–17:05 HST. Colored cells: Δ(3.9 − 11.2 µm) above the 3-day background — what the detector sees. Circles: candidates (yellow) and human-review requests (red). Rendered with OpenCV (cv2.VideoWriter, H.264).
