Like most of the countries in Asia, there is no reason why there should not be real-time Air Quality monitoring in Cambodia, at least for Phnom Penh and Siem Reap.

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.
