Jakarta's Bundaran HI and Jalan Thamrin air quality reflects the Indonesian capital's primary commercial boulevard and the iconic Hotel Indonesia roundabout, with vehicle traffic on the Jalan MH Thamrin generating some of Jakarta's most sustained urban NOₓ and PM2.5 in the city's main business district. The open boulevard geometry provides limited dispersal, while the extraordinary traffic density on this central artery maintains consistently elevated readings throughout most of the year.

When is air pollution at its worst in Bundaran HI & Jalan Thamrin?

You're quickest to notice worse air in Bundaran HI & Jalan Thamrin when tropical ornamental plantings and boulevard vegetation pollen peaks, or due to vehicle traffic on the Jalan MH Thamrin; background levels usually settle back down once the season changes.

Are air quality levels in Bundaran HI & Jalan Thamrin based on measurements or forecasts?

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
