Where these estimates come from

We show 8 selected cities in Vietnam, each at its own model grid cell. The list is not a nationwide monitoring network or national average. Open-Meteo provides the Copernicus Atmosphere Monitoring Service (CAMS) global model at roughly 45 km resolution. Nearby places may share a grid cell, and local pollution can differ.

The AQI is the provider’s modelled US AQI across pollutants. PM2.5 is a concentration in µg/m³. We do not convert a single hourly PM2.5 concentration into a daily AQI. These estimates use a different basis from the measured PM2.5-derived AQI on our Malaysia and Singapore pages.

“Valid for” is the time represented by the model, not the time a sensor took a measurement or a model run was issued. The app checks for new estimates every 15 minutes. Older estimates and saved responses are labelled; missing values remain unavailable.

For official local readings and activity advice, visit Centre for Environmental Monitoring. Vietnam’s national index may use different breakpoints and averaging periods.

About Hanoi air quality

These are model estimates, not measurements from a local monitoring station or the official national index. Each city represents a roughly 45 km model grid cell, not a country average. Local pollution can differ.

The Turtle Tower, Hoan Kiem Lake scene is an illustration, not a live camera view. Haze follows the modelled AQI and lighting follows the city’s local time.
