About this system. This dashboard monitors transboundary haze across Kalimantan, Sumatera, Malaysia, and Singapore using air quality data from WAQI (World Air Quality Index), which aggregates the BMKG (Indonesia), DOE Malaysia (APIMS) and NEA Singapore networks. The Source column names the organisation that owns each sensor. Readings are stored in PostgreSQL and refreshed every 30 minutes. Read the full methodology and limitations →
