Cambodia ranks 162nd (out of 178 countries) at the Environmental Performance Index for Air Quality. This air pollution problem, just like other countries is South Asia, is becoming even more important for World Heritage Sites like the Angkor Archeological Park (Siem Reap) - due to the hundreds of tuk-tuks and buses carrying the tourist (check this article). You can read useful advices from the US Embassy on Phnom Penh "Dirty Air", or this interesting blog post about "Air pollution is hardly Cambodia’s highest priority".
Air Quality Data availability
Unfortunately, there is not much information about real-time Air Quality data from the Ministry of the Environment (MOE). And projects like the ASEAN-German Clean Air for Smaller Cities looked promising, but did not provide any tangible monitoring result.
The best solution for providing real-time Air Quality information in Cambodia is for the MOE to start providing official hourly AQI readings. But this can, sometimes, take more time than expected.

Monitoring the Air Quality
For this reason, we are now investigating with several Institutions, Universities, Schools as well as individual citizens the possibility to setup an Air Quality monitoring network, which would allow to broadcast free hourly readings for several locations in Phnom Penh. This network would later be extended to other cities in Cambodia.
The monitoring stations used for this network are the semi-professional GAIA A12 Air Quality monitoring stations. The Gaia A12 is much more affordable than the traditional monitoring station ($200 for the GAIA A12 while it is $10,000+ for the traditional ones), but yet with a data quality as good and reliable as the traditional stations.
