Singapore Coverage
NTU, RGS, and Woodlands stations form a triangular network across the island. NASA FIRMS fire detections overlay transboundary haze; NEA air quality fuses with LiDAR backscatter on one clock.

Detection & Scoring
A two-hour rolling window is scored 0–100% from a seven-component physical model, with a diurnal boundary-layer breakthrough forecast and a three-stage cloud classifier suppressing false alarms.
