Sources & coverage ↓FL squares = reported flood event locations · Blue pins = current reported PM2.5 · gray = older than 90 minutes · orange cells = fire detections per 0.25° grid; darker means more detections, not burned area. Dashed box shows the existing fire archive coverage. Clouds or blank imagery do not mean safe.

Air-quality coverage by country
Choose a country to focus the map. Reference portals are not connected numeric feeds.
From raw data to preparation
- Raw: check provider, units, observation time and averaging period.
- Checked: separate stale readings and unconnected countries; never fill gaps with zero.
- Cooked: AOD is column aerosol; fires are signals, not arriving surface concentration. The +hour paths are wind-based air-movement scenarios, not smoke dispersion or AQI.
- Act: check destination readings before travel, prepare a cleaner-air room and follow local exposure guidance.
Reading hourly wind paths
Raw: 63 Open-Meteo hourly samples at 6° spacing, 10 m and 850 hPa → check units, valid hours and terrain → cooked: nearby wind vectors and steps of at most 15 minutes for six hours; stop at missing data → use: inspect possible air movement, not smoke arrival at home.
850 hPa is not a fixed height above ground. Paths omit terrain, plume rise, dispersion, deposition and rain removal. Predicting exposure requires dispersion modelling and emission inputs.
Open-Meteo: hourly and pressure-level variables ↗ · NOAA: trajectory and dispersion modelling ↗Regional flood evidence
Raw: GDACS episodes and report periods → checked: country, timestamps and a six-hour retrieval age limit → cooked: event locations, without inventing inundation boundaries → action: check gauges and local warnings before travelling or relocating.
Reports cover the last 14 days, not current inundation. GDACS alert colours describe humanitarian impact, not road safety or water depth. FloodDash assessments cover Thailand; MRC and ADINet are references. Yesterday’s satellite rain is not a flood forecast.
