Malaysian Air Pollution Index

IPU stands for Indeks Pencemaran Udara or Air Pollution Index (API) is an indicator for the air quality status at any particular area within Malaysia.

MyIPU is an apps that indicates the latest API readings at any particular areas within Malaysia based on standard health classification.

[Features]

- API reading are based on the nearest location with detail description of the particular area

- Information provided are updated hourly by the Department of Environment (JAS)

- Geo Location Function

- Showed API reading on the nearest or user prefered area

- Announcement Function

- Widget Function

Updating Process

-------------------

Hourly Air Pollutant Index (API) is calculated based on data retrived from remotely controlled air quality monitoring station throughout the country. Data retrival process will need a complete cycle of one (1) hour before API readings can be obtained. For example: API readings for 7 am will only be accomplished after one (1) hour data retrival i.e at 8 am which subsequently be updated on APIMS website.

Note :

--------

* = particulate matter with diameter of less than 10 micron

a = sulphur dioxide

b = nitrogen dioxide

c = ozone

d = carbon monoxide

& = more than one pollutant

API Calculation

-----------------

API value is calculated based on average concentration of air pollutants namely SO2, NO2, CO, O3 and PM10. The air pollutant with the highest concentration (dominant pollutant) will determine the API value. Normally, concentration of particulate matter , PM10 is the highest among other pollutants and determines the API value.
