Register a village, school, clinic or household location to monitor wildfire hotspots, smoke transport, PM2.5 and Acute Respiratory Infection (ARI/ISPA) risk — or load sample Kalimantan data.
Vulnerable groups: — ·
Smoke Hazard × Population Vulnerability ÷ Protective Capacity
Computed from live satellite & reanalysis APIs. âš = modelled estimate (ground sensor recommended).
| PM2.5 µg/m³ (24h) | Category | Meaning for ARI/ISPA |
|---|---|---|
| 0–15 | Good | WHO 24h guideline ≤15. Normal activity safe. |
| 15–35 | Moderate | Sensitive groups may notice throat/eye irritation. |
| 35–55 | Unhealthy (Sensitive) | Children, elderly, asthma/COPD should stay indoors. |
| 55–150 | Unhealthy | ARI/ISPA cases rise sharply. Masks + clean room needed. |
| 150–250 | Very Unhealthy | Emergency conditions. School closure recommended. |
| 250+ | Hazardous | Health emergency. Consider evacuation of vulnerable. |

Auto-generated protective steps based on current smoke levels, vulnerable groups present, and available equipment.
Automatically logs every MODERATE/HIGH smoke exposure day. Stores up to 5 years.
HazeGuard needs a free NASA FIRMS key to detect fire hotspots
It is 100% free and takes about 2 minutes. NASA gives every user a personal "MAP_KEY" so their servers can manage traffic. Without it, this app can still show PM2.5 and weather, but fire hotspot detection will be disabled — which is the core of smoke source tracking.
a1b2c3d4e5f6...Your key is stored only in this browser (IndexedDB). It is never sent to any server other than NASA's own API.
Tick the protective resources you actually have. More capacity lowers the ARI risk score.
