Jakarta air quality: PM2.5, PM10 and ISPU explained
Jakarta air quality is measured at individual monitoring stations. PM2.5 and PM10 are particle measurements; ISPU is Indonesia's unitless air-quality index. Check the station, observation time and source together: one station reading is not automatically a city-wide average.
What does the Napas Jakarta map show?
Napas Jakarta is a bilingual map and assistant for understanding Jakarta station observations. A reading belongs to a particular monitor and time. Read its pollutant, unit, timestamp and source link together, especially when comparing different locations.
What is the difference between PM2.5 and PM10?
PM2.5 describes airborne particles with an aerodynamic diameter of 2.5 micrometres or less. PM10 describes particles of 10 micrometres or less. When shown in µg/m³, each is a pollutant concentration; the two measurements are not an air-quality index.
What is ISPU in Jakarta?
ISPU (Indeks Standar Pencemar Udara) is Indonesia's dimensionless index describing ambient air quality at a particular location. It is a different kind of value from a pollutant concentration such as PM2.5 in µg/m³. Do not read an ISPU number as a concentration.
How can I check current air quality in Jakarta?
Check the station name and latest observation time, then follow the source link for the official reading. The DKI Jakarta monitoring portal publishes current station information. Napas Jakarta adds map and explanation context; use the timestamp shown by the data source when deciding whether a reading is current.
Common questions about Jakarta air quality
Can one air-quality station represent all of Jakarta?
No. A monitor records conditions at its own location and time. Compare multiple stations and their timestamps before drawing conclusions about a wider area.
Are PM2.5 and ISPU the same?
No. PM2.5 is a particle concentration, commonly reported in µg/m³. ISPU is a unitless Indonesian index based on pollutant information.
Where can I verify an official Jakarta station reading?
Open the DKI Jakarta air-quality portal and check the station and update time shown there.
