Where these estimates come from

For Surabaya, we request the model grid cell near -7.2575, 112.7521. 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 BMKG air-quality information. Indonesia’s national index may use different breakpoints and averaging periods.

About Surabaya 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 Heroes Monument scene is an illustration, not a live camera view. Haze follows the modelled AQI and lighting follows the city’s local time.
