Fires, smoke and the 2,500 ft wind, with Singapore at the centre
Tap anywhere to trace where its air goes. Drag to pan, pinch or scroll to zoom.
Wind at 925 hPa (about 2,500 ft) and model smoke (CAMS surface PM2.5) from Open-Meteo; hotspots from NASA FIRMS (VIIRS, NOAA-20), last 48 hours. Air paths follow the 2,500 ft wind only, so treat them as a rough guide: real smoke also rises, sinks and rains out.
